The lack of money shows especially on the 'street scenes'. They're always in the same spot in the middle of the 2 or 3 buildings where all the characters live, in 'the rear window' style. This is OK given the plot's nature, the problem is there are almost no extras and no sound effects of city life either, it's like a post-apocalyptic movie where half the population are dead. The main character's room is under-produced too.
Otherwise it's quite entertaining. Strangely, the movie succeeds to hold your interest during the more subdued first and second act, but falls apart in the last act, when all the action and special effects start kicking in. I think this part was ackwardly edited and isn't very effective.
The dvd has a good widescreen anamorphic transfer, and the cast's audition tapes make a curious extra.
