Fantastic for learning about new things. It's what the Discovery Channel used to be (not surprising considering it came from the same mind). I love the ease of use of the app, with "currently watching" having its own section (something most apps struggle with I find). The only downside I have found is that you seem to only be able to search for actual titles of series or videos; you can't search for David Attenborough for example, even though he is on there, which is a little nonsensical.

Not great. Literally used it for a minute and found a problem. Don't understand why a search in the app brings up more results than the web site and when you try to play those extra results it errors. Also just found out the tablet version only runs in portrait. You do know it's 2022 don't you and you should be able to write an app that works on a phone and a tablet? Can't believe I just paid for this service. What a load of junk.

I don't understand how the downloads can take longer than watching the episodes themselves. High quality is supposedly 1GB per hour. I can download 1 GB in less than 1 minute from Steam and the like. So it's definitely not my connection. Not to mention 1GB per hour is pretty bad. A reasonable bitrate would result in 2-3GB/h at 1080p. The compression artifacts on the shows I've seen were pretty bad. On top of all this, you can't even download while watching.
