Beau is Afraid was the last one I recall. I think it was mostly the latter half of the movie where I started to get a bit confused and needed the ending explained to me.
What movies made you look up some kind of explanation afterwards? I feel like I have done it several times in the past for more surreal movies but can’t think of any other examples.
It can also be a TV show.
I watched it with my partner and we riffed on it the whole time. Thoroughly enjoyable. Making fun of the movie’s bad parts allowed me to get past the boredom and appreciate the good.
