I found this movie was a pretty okay-ish comedy (?)
Completely retarded chicks do completely retarded things and pretty much all die from their limitless stupidity.

Got a few good laughs out of it, but overall nothing special.

PS.
Now they could have made this movie a very interesting one (the setup was usable) - but for that they would have needed to cast good actors and thoroughly rewrite a good part of the script.
