Critics Consensus

With shoddy FX, acting and directing. This isn't so bad it's good. It's just so bad it's terrible.

Robert P @Superbad Sep 25, 2026 This Movie stinks... See more Skramz B @SkramzBop Sep 10, 2026 This movie is just boring. So bad that I made my profile just to write this review. Just skip to the very end fight, as it’s the most interesting part of the movie anyway. You’ll be glad you did. See more Liam D @Mediawatcher2003 Oct 13, 2025 I wasn’t going into this movie expecting an life changing experience but I wanted to have so bad it’s good laughs and while they were some moments with the terrible script, flat acting and the usual Asylum awful CGI but the rest was so dull that isn’t worth watching See more Andrei S @Rumanking Oct 3, 2025 Meh, I first whached when I was a kid and I loved it, but when I see it now, dam, I did not remeber it was so bad See more Stephen C @bob25009 Jul 27, 2025 Success in 1.5 hours!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
