Friday the 13th Part VII: The New Blood (1988)
Fans hated (and continue to hate) Friday the 13th Part V: A New Beginning because Jason is not really in it (instead, it's a guy pretending to be Jason)... but, come on. If not for the last 30 seconds of the movie, no one would know any differently. Besides, I liked how, instead of killing a bunch of camp counselors, "Jason" was killing a bunch of crazy kids at some mental home.
Well, Friday the 13th Part VII: The New Blood has got to be the low point in the series, at least until Jason got a case of wanderlust and started going to places like Hell and outer space. The only thing that makes this movie stand is that the heroine (Tina, which is the perfect 80s name for your horror movie heroine) has telekinesis and the power to raise the dead (!), but the script does absolutely nothing with this until the last scene of the film.
I did, however, appreciate how evil and slimy Tina's psychiatrist is. By far the best part of the movie is where he is running away from Jason with Tina's mom. Jason catches up to them, and the guy grabs the mom, pulls her in between him and Jason, and uses her as a human shield. Although she dies rather painlessly from just getting stabbed, the psychiatrist gets what he deserves with probably the most horrible death in the film.
Other than that one scene and a great stunt where Jason falls backward not down but through some stairs, this movie has absolutely nothing going on. With a bad horror movie, you can usually look forward to some inventive lighting or camerawork, and of course some great gore effects.
Friday the 13th Part VII: The New Blood has none of that, as it looks like a high budget TV movie, and the MPAA demanded that basically all gore and blood be cut from the film to get an R rating. It's a miracle they even allowed the movie to have a Jason in it!
As far as I'm concerned, this is the low point of the series. Friday the 13th Part 3, while awful, at least had some good effects and its laughable attempt at 3D, while Friday the 13th: Jason's Space Adventure brought some excellent gore effects to keep you awake.
