Along with sharp satire and sharp commentary, Slumber Party Massacre is full of clever humor.

[Director Amy Holden] Jones tries the more effective tack of playing the slasher stuff straight and inserting clever visual jokes when she has the opportunity.

A gruesome, T&A-filled feminist tract about female fears of mature male sexuality.

Jones injects a fair amount of humor into the proceedings, but it's not always clear what's intentional and what's not, making for an occasionally confounding slasher film.
