Well, if you are looking for a serious horror film... DON'T WATCH THIS MOVIE. The acting is bad, the gore is horrible, the blood looks fake and the movie basically has a story line that has been used... about 10 times (Friday The 13th 1-10).
But, if you want a laugh.. this is worth checking out. You may get a little aggravated with the bad acting and the "it's Trevor Moorhouse" refernces. A tad bit overdone. The plot fails to tell you who he is, where he comes from, why he is killing, et etc. Trevor also turns out to be some little 5' 10" 180lb masked squirt with a chainsaw instead of a left hand (UM, EVIL DEAD 2?!?).
Anyways, watch part 2 instead. Almsot the same storyline.. better gore, blood, acting,story, etc.
