There are a lot of movies and TV shows that don't stick well in my head and sometimes I can realize 30 minutes into a movie that I've seen it before. Other films I can go and think about for decades after seeing them. I thought I'd make a list of these movies and TV series here as I've been looking for such a list myself. Feel free to write to me if you have any tips for movies or series I should see or put on the list.
The Matrix (first film only)
Interstellar
American Beauty
Undone (TV series on Prime Video)
A beautiful mind
The Truman Show
Midnight Gospel (TV series)
Groundhog Day
Avatar
Into the Wild
Captain Fantastic
