Jambli’s review published on Letterboxd:
Now THIS is an Exorcist sequel. The writer comes back as the director, and he does a darn good job of it. It's got a different tone that is both more funny at times but also way creepier and able to get under your skin. Its plot is related to the first film but still stands as its own supernatural serial killer movie. It even has studio meddling that arguably makes for a more suitable climax!
But let the man call his movie Legion for god's sake. Nothing more boring than a movie being called "Sequel 3". Otherwise "Exorcist III: The Funny Fish Story" would have been a suitable compromise.
