Jeremy of The Daily Rotation wrote, "Yes; the latest Guillermo del Toro-produced PG-13 horror film Mama is as bad as it looks. It’s actually much worse. Newcomer director Andres Muschietti adapts his own short-film into a full-length with the help of his writing team of Barbra Muschietti and Neil Cross. The result is a horrid film that relies on extended amounts of boring nothingness to keep it moving. Mama comes preloaded with dozens of cheap jump-scares and by cheap I mean the CGI is hideously done and at several points laughably bad. The only saving grace is an against-type performance by Jessica Chastain, but even her black hair and punk-rock getup can’t keep this train from derailing." (Cinema, Mama) 5/10
