IMDB

"Pajama Party" is the fourth "Beach Party" movie and by far the worst (so far).  It is wonky at worst and ridiculous at best.  Ridiculous parts: Buster Keaton plays a Native American, the plot involves an alien coming from outer space, there's a woman who dances slowly and things explode.
Sadly, Don Weis directed this instead of William Asher, who directed the other three films (and some of the films following this one).  Asher is a better director.  I didn't hate this movie, but it was not that good.  The other three are great, though.  The slow dancing woman was fantastic.  Candy Johnson doesn't use her "powers" in this one, which really was a let down.
Also, there are not a lot of pajama parties in this one.  It mostly takes place on, get this, a fucking beach!  Also, Frankie Avalon only makes a cameo.

5.5/10
