Andrew Ford’s review published on Letterboxd:
Capitalizes on the phenomenal cold open from the first film by doubling down on the whole "math killing people" part.
Weirdly feels even more low budget than the first film, and the performances are comparatively disappointing as well (not that they were ever great in the first film). Imaginative, sure, but ultimately to the point that almost becomes nonsensical.
Also weirdly derivative with some of the first film's character types, in a way that I found more frustrating than purposeful.
