I find it a bit...misrepresented to call Slumber Party Massacre a Trilogy. Yes, there are 3 of them and they do share the same name...but I found that movies have little to do each other. That is not to say that these films are bad...or rather not entertaining. Each installment in the series adds a unique flavor to the trite gathering of scanty clad, 17 ish girls getting picked off one by one scenario.
What would a gathering of stupid teenagers be without a themed based killer on the loose? It would be Glee...but I digress. In this, our cherry popping installment in the Slumber Party series the killer targets the women of an average High School with his power tool arsenal, favoring his trusty power drill. When the girls varsity basketball team decide to have a slumber party, the Home Depot aficionado is not far behind with a really long extension cable en tow. This films satisfies that gore-craving just a smidgen, being on par with tame slashers like Halloween and Friday the 13th. The dialogue is memorable and has the "so bad its good" thing that the kids keep going on about. It tosses aside the "who dunnit?" by showing you the killer while the credits are still rolling. This guy has no motive to kill, he merely enjoys it which is a much more disturbing thing than a killer with a purpose. Not vastly original but its nice to see a movie not relying on this trope. The acting or rather the eye candy, sorry that's what it is...are good at conveying the hopeless feeling of being trapped in a wide open house. The deaths are alright but nothing to write home about. Over all a pretty entertaining hour and change of 80's slasher goodness.
Slumber Party Massacre II

Slumber Party Massacre III

All together the three movies seldom make a reference to one another, that is the charm to this misguided trilogy, each installment has its own feel and flavor. This makes it ideal for marathon, themes never get old, deaths are creative and unique all the way through and the incredi-bad writing will give you some deep belly laughs.
