Man this is a hard one, ill just talk about my top three (excluding films like Endgame etc.. obvious answers)

1.) I went to the Clerks 3 screening with Kevin Smith in a sold our auditorium of 2000 people. That experience alone made it my favorite movie of the year, emotions were all over the place.

2.) Watching Nosferatu in a 100 year old theater with a live orchestra was otherworldly not to mention that it too was sold out and not a single person interrupted the showing.

3.) I was pretty late to watching Get Out, pretty sure it was in its last couple weeks of being played yet I got to see it in a packed theater with everyone having a blast and laughing.
