Not nearly as full of a meal as Jackson’s later “Dead Alive,” this no-budget shot-on-weekends first film is giddily gross and (for the most part) filled with clever little moments. Too bad the DVD didn’t come with subtitles — it’s impossible to understand what those Kiwis are saying. Brains, barf and burly men with beards abound! (And if you miss a chunk in the middle due to a phone call or something, don’t worry.)
