To comment on the software/UX side: Well one reason might be how horrible Netflix is at handling what people have watched and if something you watch has a new season (outside of the week that season releases). AppleTV start the home screen with large trailer but with a watch list just below it, and that list then will display a show you watched to the end but that a new episode/season released on. Makes it much easier to watch new seasons of shows I've watched without having to manually remember and find them. Also Netflix insistance in recommendations of content you just watched (eg not taking watched status into account) just makes this even worse because shows with no new content are on same lists as shows with new..
