The producers of Get Out and the director of The Help bring us psycho-revenge horror-comedy Ma, which shows a side of the dynamic of Oscar-winning Octavia Spencer that we’ve never seen.

Ma is about a woman named Sue Ann (Spencer) who, after being approached by a group of high schoolers to purchase alcohol for them, decides to allow them to party “safely” in her basement. She only insists on a few rules, such as they can’t take the Lord’s name in vain, and they can’t, under any circumstances, go upstairs.

At first, Sue Ann appears to be a decent woman with good intentions, who seems to be looking out for the teens “safety” by providing them with a safe place to drink. After all, a cool parent is every teen’s dream. But then, as they begin to tire of Ma’s somewhat overbearing hospitality, she transitions into a nightmare of a vindictive psycho-stalker fueled by her own childhood wounds and rejections.

While there is some predictability within the film, Ma is ALL Spencer, and she manages to pull off her usual dynamic grandeur as the revenge-seeking veterinary nurse. Other stand-out performances include Allison Janney as Sue Ann’s crass boss. The Oscar winner delivers some serious laughs with hilarious one-liners and vulgar zingers and provides much of the film’s comic relief.

Diana Silvers also delivers as the film’s protagonist Maggie, a teen who moves to a new town with her single mom, played by Juliette Lewis. Silvers, who is also currently co-starring in the excellent teen comedy Booksmart, and Lewis portray a genuine mother/daughter relationship, with Lewis getting more to chew on once her relevance to the story is revealed.

Director Tate Taylor and screenwriter Scotty Landes take all types of exciting and inventive creative liberties with the somewhat non-cohesive storyline. But for the most part, Ma is a good time filled with scares, unexpected twists, a few laughs, and a slew of stellar performances. It should give audiences their money’s worth and potentially make youngsters value the unforeseen long-term psychological consequences of their actions and the value of simple kindness. Then again, maybe not.

Either way, there are some jaw-dropping moments that prove Blumhouse Productions continues to push the horror genre in a new, hybrid direction, while simultaneously pushing the envelope in social boundaries in a post-Get Out world — and that excites us to no end.

Ma is in theaters now, grab your friends and don’t let her drink alone.
