I saw this movie around 18 years ago and then again, just recently. It's aged surprisingly well, despite the clunky, stop frame robot animation. The plot is pretty good, there's plenty of blood and gore (including a guy with his skin melting off his body) and crucially, not too much reliance on CG effects. I did not remember all the blood and gore. This movie is definitely not for kids younger than 13.
8/10
