Slumber Party Massacre (1982)

"An eighteen-year-old high school girl is left at home by her parents and she decides to have a slumber party. There is friction between some of the invited guests and the new girl, who is better at basketball than they, so the new girl decides to stay at home (which is conveniently across the street from the host's house). Meanwhile, a murderer of five people with a propensity for power tools has escaped and is at large, and eventually makes his way to the party, where the guests begin experiencing an attrition problem, with only the new girl to help them."

I ended up watching most of this on fast forward as it was so drawn out and slow that I felt my life ebbing away as I watched.

It was originally conceived as a parody but for some reason the company who made it decided to play it straight instead. It isn't funny and it isn't scary but there were a couple of nice death scenes and the communal shower scene perked me up slightly.

It tries really hard to copy "Halloween" but there's even less blood and far fewer jumpy bits.

I'd give it 1 out of 10 but really it's a complete B movie bomb.
