I found the movie hilarious, specifically the detectives, so I'm fine with a film being funny, but I didn't enjoy the campiness of the doctors in the opening. To me, the acting of the doctors and the rest of the film really didn't fit at all, and I don't like the excuse of it being used as misdirection.
I also hate when off-the-wall movies don't commit, and instead, lean on campiness as a failsafe in case people make fun of the ridiculousness of the movie...like playing it off like a joke. Commit to your ridiculousness and hit the ground running. I want madness in horror, and just because classic horrors are campy, doesn't mean you can't evolve and give us something new.
I don't know. Felt really strongly about this, because I feel like a lot of movies do this nowadays instead of adding comedy in your own voice (example: the interactions between the detectives were great and hilarious, but not like slapstick, bad acting like the opening).
