A Dolphin-spotting pleasure cruise turns into a nightmare when a tour boat is sunk sending survivors to an island inhabited by monsters from an abandoned lab project gone very wrong. With CGI at least as good as any Asylum offering, among the nasties are the titular 500' snake and her babies, a vicious school of big flying Piranhas and a massive acid-blooded Toad with a projectile Tongue that can rip the flesh from your bones. But the charm lies in the broken English subtitles and stilted acting that only the Chinese can manage to pull off with a straight face. Actually not too bad, considering what it is!
