My views on this film haven't much changed since I last saw it.
It's a quick-paced, fun, cheesy slasher movie. The 80's soundtrack is both fun and nostalgic, and the female nudity is both memorable and captivating. At under 80 minutes, this movie doesn't take long for things to begin happening, and given that the story's moderately paper-thin, that's only a positive.
The killer is a bit uninspired, but I do like the his choice of weaponry, being a drill. Gore throughout the film is pretty good, and given the quick-paced nature of the movie, it really doesn't seem like all that long a time.
The Slumber Party Massacre is a simple movie, and while most of the characters are decent, none of them really stand out (though the neighbor, played by Rigg Kennedy, is a damn cool cat), it's a fun movie that is always a good time. Not a long review, but don't have much to say. A good slasher worth watching. 7.5/10 (rounded down to 7/10 to fit site's format).
