I met Troy duffy and the two lead actors at a QnA at Drexel U the other day. They kind of quashed my fears of this movie messing up the vibe of the first movie.
Also, the first movie is by no means a ground shaking, revolutionary GOOD movie. It's appeal comes from watching it with a group of people and having a good time, because damn it is a fun movie to watch, especially if your a sick and twisted individual who likes watching cats go splat (which I'm told by sean patrick flannery there is more of in this new installment).
Seeing it in imax tonight, can't wait!
