My friend and I went to see it one night when we had free passes and nothing better to do, and the presence of David Thewlis and Michael Gambon were by far the most amusing parts. Well, and we had some interior design lust for the house in London, and some speculation about how you get on a post-9/11 plane with a pouch full of demon-killing daggers (provided by Dumbledore!). He didn't even put it them in his carry-on! He sat on the plane with a bunch of knives on his lap!
