I do a lot of my streaming with Apple TV, but the worst parts about the Apple TV app are in my opinion are:

- Too many promos of other shows before watching a show. This is often for shows I've already watched and am watching. Apple knows which shows I watch. It shouldn't need to give me promos for shows I've watched or am actively watching. - Poor UX for "Play Next Episode" functionality. If I just finished an episode of a show and I click to watch the next episode, I don't need to see the recap of the previous episode or the intro. - Speaking of intro, when you click to skip, it usually leaves you somewhere between 5 and 10 seconds from the end of the into, not actually after it.
