Just about as good a zombie movie as you'd wish to see.
Very simple set up:
Young guy gets new job in a cadaver and scientific specimen storage facility, and the older h=guy there showing him the ropes, and bragging a little (oops), tells him about the story behind the original Living Dead movie, and how those pickled zombies are now in the basement, having been contained there by the military...
...Naturally, young guy doesn't believe, older guy, showing off, takes him down to see the "safe as houses" containers, and.... well.... you can guess what from there.
Wotsit hits the doodah, and the rest of the movie is just an escalation of events from there.
I realise, from this, the essential ingredient in most (although not all, admittedly) zombie movies, over and above keeping the movie tight, economical, and short, is a healthy dose of humour, which this has in spades...
(Zombie movies that take the subject, and themselves too seriously are generally an eye-rolling yawn-fest)
...Either satire (social or otherwise) or straight up comedy suits the genre well, and allows you to enjoy the gross -out horror with a big fat grin on your face!
This one sits somewhere, humour wise, between the raised eyebrow / knowing satire of those classic Romero movies and Shaun Of The Dead, this latter one being the most obviously influenced by the tone of the humour in this, although this, itself, clearly in feel, look, and tone, feels a perfect fit with those Romero ones.
Aside from the mindless fun, this does have a pretty darn impressive thread of zombie lore and bio-logic running through it, which they didn't have to put in there, but is really well thought out, and appreciated, nonetheless.
Pretty cool alt / metal / punk soundtrack, a gang of hapless youth-punk / street trash waste-oids, brilliantly pleasing practical horror effects. which are both gross and hilarious, no nonsense, straight in zombie fest.
Hugely entertaining, great fun, and and excellent hour and a half all round.
(Another tough to find DVD too!)
