Personally, The Rocky Horror Picture Show.
I knew it was going to be quite the experience before I went for the first time‡ but it was so much fun I had to keep going back bringing friends each time.
It's still a fun tradition to do though we haven't done it since last year, we're probably going to try and go again in a few weeks.
‡ I had seen it many times before going to see it in theaters for the first time.
I’m usually the first to complain about character driven movies, as opposed to story driven. Usually I despise the former category.
Somehow, blade runner 2049 is in my top 10 favorite movies of all time. That’s how fucking good it is.
