Curiosity Stream is ok. The price is great, but the content is hit-or-miss, and it's really hard to separate the wheat from the chaff. Everything is rated 90%+ regardless of actual quality; the "staff picks" were almost certainly picked by a [bad] algorithm; the "collections" have very limited on-topic content mixed with tons of off-topic content. A lot of the videos are short; like 15-20 minutes. A bunch of them have synthetic voices, possibly using automatic translations from the original language (this is even worse on Amazon Prime); the effect is a creepy uncanny valley unease that isn't immediately apparent.

If you know something specific to search for and watch, it's a bargain, but if you just want to browse around, it can be frustrating. More often than not, I spend half an hour or so viewing the first minute of a bunch of videos, and then give up in frustration. New genuinely high-quality content doesn't seem to come around very often.

About the only reason I keep it is to re-watch the good videos I can find by searching for specific people (like my favorite physics presenter, Jim Al-Khalili). That and the fact that I forget I'm subscribed until the annual charge hits, and then it's not worth my time to figure out how to cancel.
