Is this movie really as bad as the former comments made it out to be? Personally I don't think so. Sure, the acting is (sometimes painfully) bad, the special fx are laughable and the lightning sucks (some parts are so dark you can hardly follow what's happening) but who rents forgotten curiosities like this for it's production values? And does a minimal budget, inexperienced crew and a very 'functional' script necessarily result in cheezy, grade Z 'good for laughs'-kind of movie? I strongly disagree. Somehow the B movie seems to have got mixed up with the grade Z-movie...
Anyway, to the film: the plot is about a devilish fiend (some kind of evil spirit in a human form) that has to kill people and steal their 'lifeforce', so thats it's stolen human body won't decompose. The fiend is a pathetic walrus-looking guy who spends his time giving violin-classes and listening to bad synthesizer music in his lonely apartment. The only people who get in the way of his killing spree is a nice, typical smalltown, middle class couple who of course starts playing detectives. The couple works great, and gives the films greatest performances. The actors are no professionals, but they act and look so normal it gives the film a genuine feel, and even moments of real warmth. The film has no fright or speed, so you'll have to have both patience and appreciation for the rare glimpses of creativity, dreams and simple humanity that sometimes surround B-movies like this one.
I somehow kind of ended up liking this little oddity, but don't take my recommendation too seriously - I often end up liking this kind of nice-spirited, slow horror-sleepers that nobody seems to remember. Also worth mentioning is that there is no gore or nudity, so gorehounds and fans of euro-horror cinema better stay far away.
I'll give it 5/10 for it's heart and humanity. Failure can be beautiful.
