Hot babysitter turns out to be part of a satanic cult that kills people as sacrifice. Pretty standard stuff, right?
It turns out that the movie starts with a "boom": funny, well paced, well edited and actually smart for once. Cinematography, lightening and, again, editing were innovative and riveting (somewhat remembered me of Nicolas Winding Refn) but the cutting-edge aspects died down as the movie stalled through the common route taken by many other horror movies. Along that path, absurdity grew as the originality diminished, resulting in a predictability, but once again showed improvement in the last few minutes of the film.
Still, it's worth remembering the whole experience was very enjoyable and funny. Sometimes even edge-of-your-seat tense. The few jumpscares weren't effective in the least, even though a shame, it was to be expected and did not affect my entertainment (and should not affect yours either).
This is the definition of late night flick. It's not bad enough to make you cringe, not complicated enough to give you headaches, but rather gory and funny enough to make you relax and enjoy your evening.
