Ireland may have given the world hurling, green beer, Graham Norton, and that funny dancing where the arms don't move, but it isn't exactly renowned for its horror movies. Shrooms, a psychological chiller from director Paddy Breathnach, is unlikely to change that fact.

A dreadful chiller set in the wilds of the 'Emerald Isle', Shrooms sees a group of teens run into a spot of bother when they experiment with hallucinogenic fungi: as they begin to trip out, they begin to check out. Is there any truth in the stories about murderous spirits that haunt the woods? Or is someone else responsible for their deaths?

With nasty desaturated colours, irritating performances from most of the cast (who over-act in a desperate attempt to show the world what they are capable of), frequently fuzzy visuals (used to try and simulate being whacked out of your gourd on drugs), blatant cribs from other horror films (The Blair Witch project and many an Asian ghost film), and virtually no gore or gratuitous nudity, could this mess be any more annoying?

Of course it could.

Rather than tell a straightforward scary story, Breathnach unwisely chooses to blur the line between what is reality and what is merely a figment of a drug-addled mind. In doing so, he confuses matters so much that the film ceases to be frightening. And let's not forgot about the talking cow, the daft plot device to rid the characters of their cell phones, the Jason Mewes/Jay lookalike, the inbred goat herders, and the extremely bad twist ending!!
