OK, we'll start off with the least surprising aspect of the movie, since the highly revealing trailer spells this out from the get-go. After Sue Anne/Ma buys the core group of teens alcohol for the first time — Maggie, Derrell, Andy, Haley, and Chaz — she invites them back to the basement of her home so that they can "drink safely" and "party like rockstars" without her worrying about them drunk driving (she takes their keys away and will only let them leave if they pass her version of a sobriety test). Maggie and Derrell are somehow the only ones who express concerns about this strange older woman letting them get wasted in her dingy basement. Do the Saw movies not exist in this universe, or . . . ?!
