Killer Mermaids

No prizes for guessing the nature of the beastie preying on tourists in this by-the-numbers creature feature. Here, American singletons end up at the mercy of a sultry siren when they stop off at an island fortress in sun-drenched Montenegro. As if that wasn't bad enough, director Milan Todorovic (Zone of the Dead) tosses in a mysterious, welly-wearing maniac who fillets all and sundry with his trusty (or is that rusty?) anchor. It's fairly routine horror (except for a particularly grisly decapitation) but is watchable enough due to an authentically claustrophobic location with its labyrinth of dark, dank tunnels and a cameo from Franco Nero, who's obviously channeling his inner Ahab as the saltiest of seadogs.
