Just finished watching it; found it pretty mediocre.

CONS:
The premise was interesting, but so much more could have been done with it. For one, an older cast would have led to a far more engaging story - a bunch jaded teens hanging around in suburbia is boring. Also the girl fucked three different guys throughout the entire movie. Whore tbh, didn't care for her at all. Some decent lore would have gone a long way too. There's not much explanation for what the thing is and why it does what it does and how. Finally it was just chopped together so terribly. Some scenes just went no where and then would 'cut' into another scene.

PROS:
Music was appropriate/worked. Milf tits/dry humping her son scene was good. Pool scene was good too.
