Have you ever seen a movie that left you like this?

No matter how much you thought it over, you could not wrap your head around the ending.
Maybe you still don't understand what happened at the end of Inception, nine years later.
Maybe it really bothered you that you don't know if Natalie Portman died at the end of Black Swan.
And perhaps you still have a lot of questions about how this happened in Avengers: Endgame.
