Personally, I think it should be tiered. I'm willing to pay ~$2 for older films (that's what my grocery store charged when I was a kid), ~$5 for new releases, and I expect a discount for paying month to month vs ala carte. So, if I watch one movie/week, $10/month seems fair since I'll probably watch 1-2 new releases and likely won't watch a movie every week. If I watch 2x that, then $15-20 seems fair. If I watch a movie every day, $50/month seems fair. Maybe pay extra for higher quality.

I currently pay for Netflix and Amazon prime, mostly so my kids can watch cartoons (we don't have c cable or satellite TV) and because my wife likes fast shipping (we watch way more Netflix than Amazon Prime though). I don't expect to pay more than either service to have access to a better selection of movies.

i already pay for: netlix, hulu, hbo, amazon prime and youtube premium.

so i already shell out a LOT of money to media companies, so i'm ok with pirating if a specific movie/series is not in any of those services because the owner of the movie/series i'm pirating is probably getting my money through any of those services.

You already know that answer is going to be different for everyone, so I don't know why you bother asking it.

A better question is when are film studios going to stop profiteering with their license fees and allow their works to be available on any platform (instead of meticulously negotiating with one platform and moving around every couple months).
