If you take in account that most of the people involved in this film where in there 20's at the time, this is a major accomplishment. It's extra gory and very funny, and some special effects are amazingly well done. It's also worth mentioning that the total budget was U$S600 and it was shot with only one camera. Most of the editing (90% of it actually, according to their website) was done while filming, i.e. filming scene number 17 right after number 16. I could say that the story was under-developed, that the acting was flaky, etc... but once again: they were 20 years old!.
If I'm not mistaken, it's also the first Argentinian zombie film. Bound to become a cult classic.
Rating: 8/10
