The content is probably fine, catering for a wide range of tastes.
The app however leaves a lot to be desired so suggest not upgrading to a 'premium' experience until fixed.
Plays the adverts quite well then fails to play the actual content, either displaying the buffering sign or simply crashes, multiple times over the past few days.
Fails to keep track of where the viewer is in series/episode kind of important when watching boxsets ie loses track in an episode fairly frequently (recently).
This is on a Fire TV Stick 4k with no known Internet issues ie Prime and BBC ultra playback fine.
