What’s a movie that completely rewired how you watch movies after you saw it?

Not “favorite movie.” Not “best movie.” I mean the one that changed your taste, your standards, or the way you notice things on screen.

For me it was Children of Men. I went in expecting a grim action movie and came out noticing blocking, long takes, sound design, and how little a film actually needs to explain if the world feels lived-in.

After that I started watching movies differently. Less “what happens next,” more “how is this shot, why does this cut land, what is the movie doing to me.”

Curious what yours was.
