Logan
Fury Road
Mother
Winter Soldier
Don't Breathe
The Neon Demon
Scott Pilgrim
Force Awakens
These come to mind. In terms of intensity, quality, and surprise.... Left the theater having adored them, instantly feeling like I just saw something special that I'll actually care about for a long time (vs. most movies just being enjoyable/probably won't watch again)
Seems like a long list but I go to the theaters fairly often. Easy to impress I suppose
