The humor and acting was great. I ended up watching the movie for the first time afterwards and it brought it all home. This performance is true to the original and much, much more.
What I didn't like
Sometimes a little over the top with the acting in certain scenes, BUT, it is a parody of a bad / awesome movie so it is hard to judge if toning it down would hurt this performance.
My overall impression
Overall a very fun experience. Highly recommended!
