I just gave it a six too. I don't know what everyone liked about this one. I sometimes get tired of the constant references to other films they've riffed, but it doesn't bother me too much if they are in the context of the scene. There were a few times in this one where the reference had no context, and didn't make any sense to me. Maybe I'm missing something: a spaceship is flying away and someone says something about stopping by Hogwarts. Also there was a line about Over the Top that seemed a little weird, something like "that's what I call over the top" or something.
I have loved all the riffs from the last few months except Avatar, but I don't only complain, I'm gonna go give the Goblet o' Fire one a 9 (or a 9.5 if I can) right now!
