I disliked parts, but I loved others.
The premier, though, was the funnest thing I've ever attended. We played Quiddich, HP trivia, dueled, made SO MANY Harry Potter references, and just plain old talked.
And there was this guy and we asked him what his shirt meant and he looked like he was going to kill us for the rest of the night. We were actually scared of him, and we ended up hiding xD
