Despite myself, I enjoyed this film. It's got a lot of action, some spooky scenes, some horror. Unfortunately, the special effects have not aged well. They might have been sub-par from the start, but today the wall-crawlers clearly look like old-school video game content embedded into a film--they look so bad it's not even scary. Granted, the film is pretty old now, but this was like 10 years after Jurassic Park, so some criticism is justified. I enjoyed it and can recommend it to zombie horror fans but it hasn't aged well.
