The ratio of gnarly infections and guts-splaying mayhem per screen minute is an important metric for zombie movies. While I am yet to analyse the data in a scientifically sound way, I can confidently declare that, on these merits, Wyrmwood: Apocalypse is a resounding success. The film is a perversely colourful, visually energetic and proudly splatterific sequel to its 2015 predecessor, a lean and mean midnight movie that, while stuffed with familiar genre elements, had a couple of rare or rare-ish distinguishing features.
