It's not a good sign when the writer/ director publicly disowns a movie after being denied his request to have his name removed from the credits, but that's when happened with CABIN FEVER 2. I don't know anything about this Ti West dude, but if he made it and he hates it then it's a pretty safe bet that the movie is gonna suck.
I actually liked the first one cause it was kinda an oddball movie that was something different (sadly nothing good can be said about the rest of Eli Roth's career, 2001 MANIACS was one of the worst things I've ever seen and the only good thing about HOSTEL was Takashi Miike's 3 second cameo). Part 2 though is just a disaster. With a name like "Spring Fever" I was expecting it to happen on Spring Break with a bunch of hot chick's in bikini's, but no it's just a lame and very short tale of the water supply from the original making local high school students sick. After the opening scene there is zero action for nearly 30 minutes then the prom starts and people get sick, puke, bleed and die. It's very lame and the story is pretty much nonexistent.
The only thing that I even found interesting was the lead actor dude was the corpse rapist from DEAD GIRL. Other than that this movie could disappear off the face of the Earth and nobody would give a fuck. Skip it. Also when I say short I'm not bullshitting the official runtime says 87 minutes, but that's misleading cause it's more like 70. They padded it with the lame intro and shitty credits for probably 5-8 minutes and then the horrible tacked on strip club ending that was probably 10 minutes long and fucking looked like it was filmed in somebody's living room. Avoid this movie!
