This is an odd movie to review. It tries to be a teen horror comedy, but it definitely struggles to find a home in any genre. The plot is quite thin and is just there to lead the characters into one comedy situation after another. The cast (including a very young Ryan Reynolds) all play their characters well, and the whole thing reminds you of those great teen comedies of the 90's (Encino Man, Bio-Dome, etc.), but it is just not as good. The horror and gore is completely non-existent to the point where the really good ideas (like the reanimated mouse) are completely underplayed, and even the sequences that are a little 'darker' in tone are soon over and never really exploited. But with all that said, this innocent little movie still struck a cord in me, and I actually quite enjoyed the lightweight fun of it all, and I have to admit that there were bits in it that made me giggle to myself.
