  I gotta agree, for average movies, yep, 90 minutes seems approachable.
context: It really depends on the script. If you have a small story to tell, 90 minutes is fine. If you want to tell 6 storylines in different places, like the last Star Wars trilogy, you'll end up with characters and plotlines that noone cares about. Because you don't have the time to get invested in them.
  I enjoy a film that takes the time to tell a story. It's fine when it's slow or when not a lot is happening. It really gives you the time to become part of that world.
  I probably sound like an old man (i'm in my 30's), but these days most mainstream movies are edited super fast. As if they are afraid to lose the audience when there is no action for 5 minutes.
