Just one movie shows how the situation is nuts:
Baahubali is a very long movie that was split into two parts. It is not a normal "movie 1 + sequel", it is basically a 5 hour long movie split in two for easier production.
Netflix originally had both parts, it is where I watched it. I went to show the movie to my wife and found out now only second half is there. The first half is on HBO, that doesn't have second half.
So to watch one movie you need two subscriptions!
