Inception
One of the coolest details in a movie (ever) is the subtle fact that DiCaprio where’s a wedding ring whenever in dreams, but not in reality.
I think the fact that they used the Inception of Maul to tie the fact that DiCaprio has guilt over her death, as well as his confidence in knowing Inception could be done is so cool.
I absolutely mind-f* movies, and nobody is better at that than Christopher Nolan. The GOAT of directing (in my opinion).
