I would totally buy tickets for the midnight showing if I didn't have to work the next morning. My husband and I did go to the first showing (12:00 a.m.) of Harry Potter and the Prisoner of Azkaban when that came out two years ago. It was really cool to see all the hardcore HP fans out there!!
I did get together 20+ friends to go see Goblet of Fire next Friday night, when we all don't have to work the next morning.
I can't wait to see this one!!
