Aterrorizante

Yes there is almost no plot and it's very nihilistic and gratuitous, but it makes up for that with a truly creepy villain and some very well done and incredibly brutal gore effects.

The acting is perfectly fine. Nothing amazing, but it's perfectly acceptable. A lot better than you usually get in a low budget horror these days.

This isn't a movie that's going to revolutionize the genre, but it's a fun throwback to the good old days of unstoppable silent killers terrorizing people for arbitrary reasons.
