I'm a lightweight and I like shorter movies because I'm impatient. I want to get to the ending in case I hate it. And my post-USSR self is afraid of timewasting activities and not having fun
efficiently enough because I need to get back to work.
Plus I grew up watching Disney.
I recently watched Marx Bro's hilarious
The Cocoanuts (1929) which near-immediately became one of my favorite comedy movies ever, and I checked the length of it. It's 1 hour 37 minutes.
I remember
Singin' in the Rain (1953?) always felt too long to me. That one's 1 hour 43 minutes. Huh. I guess they didn't use their time wisely.
The most visually memorable and stunning movie I've ever seen,
The Silent Enemy (1930), is 1 hour 24 minutes.
My favorite story and most-watched movie of all time,
The Truman Show (1998), is 1 hour 43 minutes.
For something more modern/normal, I recently enjoyed
Enchanted (2007). For the most part, very good, excepting the weird ending. That one's 1 hour 47 minutes.
So yeah seems like 1 hour 35ish is my sweet spot.
