In the opening scene of The Devil, a woman performs a magic ritual on a man covered from head to foot in erupting boils and lacerations; she opens up his stomach with a knife, fishes around in his maggot-infested guts and removes all manner of muck before patching him up. After this promising start, the film goes rapidly downhill.
The rest of this dreadfully inept movie deals with the tale of an avenging ghost whose victims cough up bucket loads of snakes and multi-coloured goop before finally kicking the bucket. Although this sounds like a gorehound's dream-come-true, the effects are lame and the excruciatingly awful scenes between the 'mucky' bits would test the patience of even the most obsessive horror fan.
In fact, the only reason I can possibly think of for recommending this dreadful film to anyone is that you will get to witness one of the most bizarre cinematic characters ever in the form of 'Ding Dong', the annoying camp bellboy; his outfits are so gay they will have you sniggering uncontrollably.
So. if you wish to see a small boy sporting tight white shorts, braces and a cap, or a fetching Sgt. Pepper style uniform, go ahead and enjoy; otherwise, I would stay well away.
