I went in blind, and boy am I glad I did. I never got spoiled regarding who the killer is, but mostly I loved how self referencial it was, and I loved how some comedy came out at unexpected moments.
Also, that cameo by Wes Craven wearing a Freddy Krueger shirt was gold.

One major complaint would be the Shaggy (I mean Stu) character, who was a bit much.

I honestly didn't expect to like it as much as I did, and I'm now looking forward to seeing the rest of the franchise.
