The Acting
The acting was hilarious, and got progressively worse as the movie went on. The three standout parts, for being particuarly atrocious/hilarious:
The scene with the girls escaping outside in the rain to see Ketchum.
"I'm going to check the back doors locked, you two check the windows, and here give me one of those knifes - I think we will be needing them"
"Oh my god, the drain pipe, hes going to get in through the attic"
I mean, the last line the girl practically sang it, it was hilarious. The terrible acting made this movie even better.
