The TV app is the single greatest feature of the Apple TV, though. I have one list of shows I am watching (sans Netflix because they are petty, I don’t subscribe to them for more than a month at a time to binge a few shows though); multiple, even, because each person in the house has their own.
P.S. They made the homescreen button goback to A the Apple TV app a while ago. This behavior can be changed go make it go back to the home screen.
