How about all those movies where the critical consensus is that it's overlong and needed to be tightened? That the mediocre 2:10 movie could have made for a great 1:40 movie?

Directors aren't infallible. They frequently make movies that are too long. Making the most of my two hours sometimes requires playing some of the overlong parts at 2x speed, because they often don't pay dividends at all. It has nothing to do with "putting in the work of paying attention", it's just not worth it.
