Love HBO but this app needs work on it's functionality. The UI is great, clean and unique enough from others. The ux on the other hand can be improved. It can't rotate the screen, the user is forced into a specific landscape side. This is the only app I've seen that can't do that. The closed captioning is atrocious. It lags. Cuts off. Shows up late. Syncs totally wrong. Not accessible at all. I always seem to have problems casting as well. It pauses a lot. The film selection though is fantastic.
