Like another user giving 5 stars to fight against the inexplicable flurry of 1 star reviews. 4 stars legit though, very entertaining throwback slasher flick with all the trimmings. If you’re criticizing the plot holes or character motivations maybe this genre just isn’t for you. Friday the 13th, My Bloody Valentine, Hatchet etc etc... the plots don’t make sense, secondary characters are supposed to be cheap stereotypes so you don’t care about them getting killed off, and the victims obviously do all kinds of dumb stuff before they die in awesome ways. That’s the job! And I had a blast watching it. Great practical effects, a bonkers backstory for the killers, the dorky dude you feel bad for and a “final girl” you’re rooting on all the way. Recommended for genre fans, as long as you’re not expecting something more that it’s not even trying to be.
P.S. Turn off the awful dubbing and watch it in the original Polish w/ subtitles! The English dub is super distracting and very mediocre - give the actors their due and keep their voices in the movie, reading ain’t hard and it’s way better all around this way!
