Pretty much every popular movie from the mid to late 1960s and basically all the 1970s.

Birdman. I found it irritatingly self-important and boring.

Lord of the Rings 2 and 3 I found to be quite meh.

I really loved Fellowship of the Ring, the other two sequels were just 90% large-scale NPC army battles that got really old really fast.

Also Rashomon (1950) sucks.

The series Schitt’s Creek is like this. It’s not knee slapping hilarious about it just memorable characters and subtle humor
