Tyler Myers’s review published on Letterboxd:
Malignant is unlike any James Wan horror film he's done, and I mean that as a major compliment. The movie is less a supernatural ghost tale like some of Wan's previous work and more a gory campy creature feature. The movie starts off as a creepy and disturbing film with strong direction and good atmosphere. Annabelle Wallis also gives a very strong performance and this is easily her best film role yet. However, while the first two acts are really solid and intriguing with a good dose of camp, the third act is balls-to-the-wall insanity that goes in places I didn't see coming that could be a dealbreaker for some, but I ate it all up and it put a big goofy grin on my face. It elevated this film to a whole new level of insanity that I didn't think it'd go but I'm so happy it did. The score by Joseph Bishara is also a major standout and has a nice mixture of old school terror and to my surprise, 90s rock grunge. While it might not be as straight up terrifying as say Insidious or The Conjuring, it still works as a totally bonkers, extremely bloody, and wholly entertaining horror feature that unlike the Conjuring movies (which are still great) wears its R rating loud and proud. Welcome back to the horror genre, James Wan.
