Greg Dundee’s review published on Letterboxd:
Ma is a movie with a lot of potential. Octavia Spencer is incredibly good in the title role; balancing the line between charismatic and insane in a way that makes me think of Kathy Bates in Misery.
Unfortunately the movie stops just short of being really good. There are several plot holes that are very noticeable, and the film overall just feels very reserved for what could have been an all out crazy horror fest.
Ma is still an enjoyable movie though, and worth watching even if just for Spencer’s performance.
