They're all confusing and clunky. I don't expect that to change. All UI today tries too hard to be confusing and clunky (gesture controls, flat UI design where you can't tell a button from text, and so on). It's like everyone has run outta ideas. Go back to the old Amazon Instant UI and everything would be fine. It's not like that had to change.
Maybe I just cannot understand the purpose of constant UI 'redesigns' where you end up with a worse version than the last and have to constantly re-learn where everything is. Why not just pick one and leave it alone? That way people can keep using what they're used to the way they always have been.
It's a streaming app. I only has to do one job. Have a selection of shows and the ability to play them via the Internet. Why must it get overly cluttered with scrolling carousels of shows I'll never watch, ads before every show they license on the platform (yet still charging $16 per month) and laggy performance? Just have a grid of tiles and buttons to start playback. Simple!
Even better, offer the user a choice. Do you want the new UI or not? Or even have the oldest version available for older, lower spec devices (such as those on Android Go or older iOS). Why not try to satisfy more people over less?
