Yeah definitely The Prowler, with Maniac close behind. People today are still shocked at how real the effects look in The Prowler, especially that pool throat slashing. ~Matt
The FX in The Prowler is excellent, yes but outside of the death sequences the movie is pretty dull and boring. So I'm going to go with F13th: TFC simply because it's a better film.
I don't care. I went with TFC because not only is the FX excellent but so is the movie. Can't say the same about The Prowler.
