We went this weekend and really enjoyed it. Was fun to catch all the little references to the earlier movies - ones the youngin's didn't catch since they were so young (or not even born) when the first one came out and really haven't watched the DVD all that much.
No previews worth commenting on (i.e. no upcoming JD movies), BUT the pre-show slide show had an interesting "quiz" question... "Who said: Nobody move. I've dropped my brain!" (I do believe it's "me" brain, but that's how they posted it).
I just took the kids this afternoon. We liked it. Just pure entertainment!! My daughter and her friend went just to see Shia LaBeouf. He looked cute. They were happy.
