Ma, you crazy bitch!

Ma (2019) is a new horror movie by Blumhouse, because if a movie comes out theatrically, there's a good chance it's made by Blumhouse. They've become a rather solid company these days, and they yield generally positive results, IMO.

Teens need to party, and a woman lends them her basement. However, this woman is mentally unbalanced for generic reasons you've all seen before, and voila! There's a premise to abide by.

Again, it's nothing you guys haven't seen before. Bullies made her psycho and it's only a matter of how far she goes with it. Fortunately, the performances are pretty good, so you can bear with, and there are a few decent scenes of "horror". You might even get a good squirm out of them, too.

Not bad.
