In the mood for a particular movie or show but don’t know which streaming service it’s playing on? That’s where JustWatch comes in. Just enter a title and this site will list all the services that offer it, along with prices. — MF

I’m a Netflix subscriber, but the built-in title browsing isn’t great. I use instantwatcher.com, which lets you browse and search shows and movies in many different ways. — MF

Netflix bases its recommendations on what you watch. If you want to change what its algorithm sees, or if you are just curious to see everything you’ve watched on Netflix, go here. You can delete a show from the list by clicking the X next to it. I was surprised to see that the oldest item on my list was Phineas and Ferb the Movie: Across the 2nd Dimension, which someone in my family watched on 12/12/11. — MF

I am wallowing in the deep motherlode of enthusiasm that is YouTube. Here are three ultra niche channels that I subscribe to and keep coming back to for more. One is FliteTest, where they turn almost anything into a flying object, from a pizza box to an Ikea chair. Another is Steve1989, with 600,000 subscribers, who collects and eats vintage military rations and ready-to-eat meals (MRE). Yes, he’ll try that ancient WWII snack box. If he is happy, I’m happy. The third is AvE, a faceless Canadian who takes apart old tools and motors while delivering commentary in his own private language of creative swearing, potty-mouth talk, and the most astounding technical knowledge I have encountered. — KK

Here are 10 hours of oceanic video. Just ten uninterrupted hours of relaxing underwater scenes of fish swimming and bubbling sounds. No narration, no drama. I watched more of this than I thought I would. Outtakes from the BBC’s Blue Planet series. — KK

If the genius artist Escher could make a musical 3D video it would like this one by mathematical explainer Vi Hart. You can move around in all 360 degrees of a 4-minute piece with 3 overlapping piano performances by a recurring Vi Hart. Watch the making-of video to appreciate the mathematical beauty of its recursive complexity. — KK

For something completely different in movies, I recommend the intensely dark comedy The Death of Stalin. As the New Yorker said, its humor “is so black you could pump it out of the ground.” Normally trivializing evil is not something I could enjoy, but this story, loosely based on historical facts, is so over the top and well done, it was funny. Laughing at the horrifying atrocities seemed the only sane response. The movie skirted the soul’s edge, but it worked for me. Available to rent on YouTube. — KK

I’ve been watching Halt and Catch Fire on Netflix, a TV series that ran for four seasons, from 2014 to 2017. It’s like a non-comedic Silicon Valley and is about a team of misfits (led by a guy who looks and acts like a psychotic Don Draper) who are trying to build a 15-pound portable computer during the PC computer revolution of the 1980s. Each season is better than the previous one. — MF

My mother-in-law is 90, doesn’t speak English, and lives with us. She and I enjoy watching the new season 3 of BattleBots on Amazon Prime. This mindless machine-on-machine violence of robots demolishing other robots is universally entertaining, and spectacular. No language needed. — KK

This cool 9-min video story, Fire in Cardboard City, is enjoyable in itself, but I really like it because the creator hacked an Xbox Kinect to do extremely low-budget motion-capture that looks great, proving how far amateurs can go today in film. — KK 

I wasn’t sure I wanted to watch another series of cooking shows on Netflix, but I wound up devouring the entire 8 episodes of Ugly Delicious. Featuring chef David Chang, it’s a personal and idiosyncratic investigation into the kinds of foods that are taken for granted, from home cooking, to low-brow favorites like pizza, to foods that don’t get much respect, like fried rice. There’s a lot of Chang in it as he bounces around ideas (and locations around the globe), but he is honest, questioning, searching, and always interesting. — KK

I really enjoyed Dave Eggers’ fictional book The Circle, but the movie is even better. This is a disturbing forecast of where always being on social media will take us. A place so transparent, it may be too clear. Much like a Black Mirror episode, but more plausible. The villain, deftly played by Tom Hanks, is likeable and relatable. I have said some of the things he says. Set in today’s Silicon Valley with perfect pitch, the story seems inevitable. If you are clicking on your phone more than 3 times a day, you should watch this. The Circle is now streaming on Amazon Prime. — KK

I’ve been laughing in awe while watching the new sitcom series, The Good Place. It’s funny, unconventional, unpredictable, original, and deeply philosophical. What’s the point of being good? Wouldn’t heaven be boring? What’s the best answer to the “trolley problem”? Yes, existential humor! It runs on NBC, but the last two seasons are available on Netflix. — KK

I’ve watched my share of mountain climbing documentaries. A new one, Meru, streaming on Netflix, is among my favorites. Meru is a stone fishtail peak in the Himalayas that had remained unsummited until recently because it required climbers to haul their own 200 pounds of gear for the final overhang wall routes. The lure of this doc is that it includes an intimate record of two attempts by the same team, the first one failing within 100 meters of the summit. It also documents unbelievable disasters and horrors the climbers endured before starting the second. Because two of the three ace climbers happened to be world class photographers (one works for National Geographic), no other high adventure has been this well documented, or as beautiful. The climbers are intelligent, warm and humble — and obsessed. Meru is a stunning experience, expertly crafted, comprehensive in capturing all moments, yet briskly edited, and a joy to watch. It entails the most innovative, thorough, and brilliant photography I’ve seen in any documentary. — KK

We are entering the century of China. Our collective future is dependent on its future, and China’s future is highly constrained by its past. By far the best history of China so far is a 6-part BBC experience now running on Amazon Prime by the peripatetic historian Michael Woods. The Story of China boasts incredibly high production values, filmed in China. A thousand-year history is grounded in visits to the actual places where it happened, making it visible and intimate. More importantly this program presents an understandable history that sadly even most Chinese today are ignorant of. Woods is a likeable host who will make you smart. I consider The Story of China essential viewing. (His Story of India is likewise great.) — KK

Deep in the basement of Netflix is a very funny Swedish movie called The 100-Year-Old Man Who Climbed Out the Window and Disappeared. Subtitled in English, I found the humor translated well into American. It’s sort of a Swedish version of Forrest Gump meets Mr. Bean. This big hit in Sweden was playing on Netflix streaming but now is on Netflix DVD only. However, last year they made a sequel that is almost as good, The 101-Year-Old Man Who Skipped Out on the Bill and Disappeared, and this one is currently streaming on Netflix. — KK

I’m eagerly looking forward to season 3 of Colony, a science fiction thriller about a world under lockdown after aliens arrive and take over. We never see the aliens — the oppressors are the humans who have cut a deal with the aliens to administrate repressive and cruel martial law in exchange for better living conditions. The story centers on a family trying to survive in a militarized, walled-off Los Angeles, where the smallest infraction is punishable by death. — MF

The best science fiction series now going is The Expanse. It’s set in a plausible 200-year ahead horizon, a period where Earth, Mars, and Asteroid Belters are in conflict. The everyday details of life in 2200 are well defined and worn convincingly; the characters nuanced and realistic, with no glaring villains. The science is sound, the production values high, and the plot is a detective thriller. The first two seasons are free to watch on Amazon prime. — KK 

In a sleepy Australian town, a group of long dead people come to life and dig themselves out of their graves. Unlike traditional zombies, they are intact, both mentally and physically. They are as confused as the good natured sheriff who becomes their protector against people who wish them harm. Can’t wait for the next season of Glitch, this intriguing Netflix original series. — MF

The Mask You Live In is a heartbreaking glimpse into how the media and ideals of masculinity are affecting young boys in America. The most poignant part of the documentary for me were the interviews with San Quentin’s Juvenile Lifers. They shared their experiences, and regret, about how being unable to articulate and share emotions as a child contributed to their rage and subsequent crimes. — CD
