I've seen this too many times: endless scrolling to try to find that one decent movie that comes free with the subscription.
But movie studios aren't stupid. They don't just give away their best movies for free. So those who simply aren't willing to pay are left watching Hitman or The Quake (fine Hulu content).
The price of movie rentals might seem high, but life is far too short to waste it watching things you don't even like that much.
Also: iTunes in particular happens to have very decent staff recommendations (i.e., actual human curation). I wouldn't be surprised if movie rental services like iTunes understand that their customers are looking for quality and not quantity, otherwise those customers would be on the streaming services.
