i liked this movie.its not completely original,but than again most movies today aren't.i liked the tense atmosphere it had.it also has some moments that get your adrenaline pumping.the acting was pretty good,in my opinion.there's not much in the way of character development here,since the movie jumps right into the action fairly quickly.but that didn't bother me in this picture.you get enough of sense of each person as the story goes along.the music is not memorable at all,and i'm not sure if that's good or bad.overall,this was not a bad movie.in fact,i'd say it's pretty decent,especially for a lazy weekend,when you have nothing else going on.for me,Altitude (2010)is a 6/10
