I'm pretty sure it's intentional, honestly. The writers are brilliant. They managed to parody both Jason and Freddy (in one of them, two kids actually dressed up as them only to be killed off by better versions of their weapons, Freddy had a machete while Angela had a chainsaw, and she had some real claws as opposed to fake for the other kid) as well as keep coming up with clever way (often poetic justice) to kill off most of them. And the fifth movie, Sleepaway Camp IV, from what I saw was just poorly pieced together footage from the first three films to kinda tie together a plot in flashbacks, making a sort of bad indie vibe.
Blair Witch, on the other hand, I fully agree with that one rating. Pseudo-amateur photography does not a good film make.
I saw two horror genre films that were pretty good. One was called Frozen (not to be confused with the Disney musical, this had three ski buddies try to game the system, and wound up stuck on a slope when it turned out the place closed for a full week, it had alot of creepy slow dread that not many horrors have and alot of character development) and the other Feng Shui (2004, it was a a Filipino made one, but the ending twist was great; it basically involved a woman buying a cursed Ba Gua mirror that brought good and bad fortune in huge amounts). The second may be hard to find, though I think Netflix had it. Nvm, Prime Video you can rent for like $3.
Oh yeah, and ZomBeavers (surprisingly scary, since they pop out of nowhere and they didn't find ANY way to kill them, but it also had a silly premise that those bitten slowly turn into beavers) and Konchu Daisenso (aka Genocide, aka War of the Insects 1968, gets points both for being a disturbing movie about bugs and for the fact that it involves a nuke blowing everyone up; it seems hard to find though, I only saw it on TCM).
(To parody the Dos Equis guy)
I rarely watch horror movies, but when I do, I like them interesting.
But yeah, I do not like over-the-top violence and gore, I like the sort of hopeless dread that you get from Lovecraft films, where the real monster is something really beyond the killer/monster (what was so interesting about the Sleepaway Camp series, the pervasive sense of something seriously wrong with the campers far more than Angela). I also like the idea of building this sense of complete terror slowly over the entire movie until at last you are completely shaken. The sense I like to get is when you play Final Fantasy and turn critters into stone for hours straight only to have a vivid nightmare of your family getting petrified watching television (actually had one of those). The slow creeping intense horror is far more terrifying that a monster or evil man. Needless to say, I was far more affected by the Dark Cell than by Bloody Mary.
