Friday the 13th Part VII: The New Blood -
5/10
Other than the needless wrinkle to the established franchise formula in the form of a psychic girl struggling to control her powers, this was a fairly standard entry into the series. The means of resurrecting Jason was definitely over-written, but the kills were all solid, the characters well enough (at least as far as the seventh instalment in an already shakey slasher franchise goes) and the unfolding events reasonably enjoyable. When push comes to shove, it's really only on the lower-end of average quality.
Friday the 13th Part VIII: Jason Takes Manhattan -
3.5/10
This was the point that the franchise stopped even trying to make sense (my personal favorite WTF moment: when the sewers of New York flood with toxic waste every night at midnight with no negative effects to the surface dwellers only a few feet above). And that's really sad, because I think that it has one of the best premises of the entire series: Jason on a boat. It's a cramped, claustrophobic setting that really offers no place for his victims to run to; it's also a more labarynthian setting, naturally seperating and sectioning off the teenagers for easy pickings without them being complete morons in the process. It's really so much wasted potential, and becomes especially unbearable when they reach the city.
Jason Goes to Hell: The Final Friday -
2/10
This film is unquestionably the most needlessly confusing, least sense making film of them all. It bends over backwards to try to do something different and utterly fails with every attempt. It suffers from Part V's major shortcoming of not actually including Jason Vorhees, but tries to sidestep that by giving him some incomprehenible power to possess living victims. It tries to overthink a simple slasher film with the same style of exaggerated plotting from Part VII and is about as poorly realized as Part VIII. It is, in short, an absolute mess, but surprisingly not the worst one out there.
Jason X -
1.5/10
This is hands down the worst
Friday the 13th movie of them all, made at a time where launchig horror icons into space was all the rage, with a tone that comes full circle to a semi-frequent self-parody. The CG was God-aweful, the cybernetic Jason conceptually stupid and the characters insipidly one-note. Far too many deaths occur off screen and most of the ones we do see are questionably tame.
