Jeremy Crabb’s review published on Letterboxd:
Ma is a fun little thriller with a fantastic performance from Octavia Spencer. It's nothing great necessarily, as the script could've used another rewrite, and there are some predictable plot development, but it's very entertaining, and it was clear that everyone was having a blast making it. I thoroughly enjoyed this. You don't need to see it in theaters but you probably won't regret it if you do.
