This was pretty much more of the original which I thought was hilarious. This one added the dimension of the main characters mothers and added the whole Christmas part to the equation. The laughs were still there and Katherine Hahn still stole every scene she was in. This was a textbook sequel to capitalize on the success of an original. Don't reinvent anything. Just give the people more of the same with little tweaks or additions.
I very much enjoyed this movie and like these characters. It's a great watch for someone wanting to see an adult movie with christmas flair.
