I went to the 12:30 showing. PACKED theater, Me and one other guy did the trivia challenge (i lost lol) and there were several people dressed as Marty. It was a total blast! Yeah, the poster could have been better, but it was still a great experience that I'm going to remember for a long time to come. The audience reactions were the best part. Applause when the movie started, cheering when George knocked out Biff. You could tell the room was filled with people who loved the movie. It was just great!
