It just ended up feeling like a kind of disjointed, slow sketch comedy American Horror Story.
The whole movie felt too flat and blunt. It's like they thought up clever or funny ideas, but threw them out in the simple way possible. And then they made sure to let them linger, as if they were pausing for audience laughter. Hell, sometimes it even felt like a laugh track would improve the movie.
I mean, the "Scary Movie"s are full of those broad and cheap laughs. This on the other hand, is quirkier and WANTS to be more than that. And unlike the Scary Movies, it DOES feel like one whole story, instead of a bunch of sketches spoofing horror flicks. But every scene felt like it dragged on for too long, way past when you "got" the joke and were ready for them to go deeper or move on or add more layers or something. And that made it come out stale. Over and over, it took you out of the movie, and reminded you that this is just a bunch of funny friends who went out there with a camera and a simple idea to have fun. That idea...just happened to only be 20 minutes worth of story and gags, that they had to stretch out to an hour and a half.
And as much as I could respect the kind of story they wanted to tell, the ways they were trying to milk comedy, and the characters they created...it's just not well edited or put together. There's not enough story, the jokes were too on the nose, and I left it kinda disappointed. This had a lot going for it: great cast, clever creative people behind it. But you might be better off just watching "This Is the End" instead.
Oh, and a certain scene with Riki Lindhome was really random and fully appreciated...
