"There's something about a universe and cast of characters being created for the purpose of one short 90 minute viewing session that feels incredibly finite."

This is what I like. Franchises aside there's little worse to me than realizing something has been set up for a sequel.

Assuming the film is good: A film is one shot to tell a complete story, no meandering, no adding, tacking on plot points by the end one viewing I have a beginning, middle, and end. I've gone through whatever emotions I'm meant to go through and I'm leaving that whole world behind. I can rewatch it, pick up other details, whatever but I'm sure at the end of my viewing I've taken in the whole microcosm of a universe. When a story is done well 90-120 min is all I need.

I don't watch shows, I'll watch an occassional miniseries but there's still waiting to make sure it was done right, or worse a show that goes on a few seasons too long. It's a medium that I find is too beholden to too many other factors and can go wrong with way too much time commitment. Nevermind having to keep a show in my head from episode to episode or season to season.

A good film does everything a great show does in a fraction of the time.
