Just saw this....horrible! SPOILERS
This movie is absolutely awful! I think the plot is fairly decent but the way it was executed sucked! I didn't like the singing at all and none of the actors could sing! At first, I thought the hunters were the killers and they were cannibals because of all the wendigo talk during the movie. However, the hunters were just a distraction (nice touch). It is revealed that Nick is the killer and basically knocked off his whole band because he had a side deal going on with a record producer. This was made clear near the end of the movie as he was singing and playing his guitar they showed blood on his hands while the last surviving girl was running for her life!
In the end, the music producer told him I'm glad you got rid of that band so obviously Nick premeditated the whole thing. I suspected him when he wanted to get rid of all cell phones and communication of any kind! Who does that in the middle of no where?! My suspicions grew when he was very displeased when their friends showed up in the woods. Nick wanted full concentration on the music so he could steal the songs and take all the credit. He was also very familar with the woods b/c he told one girl that he and his brother use to come there to fish and hunt when they were younger. What I did miss in the movie was how his brother died and he said he was 14 when he died (if any of this was even true).
Anyways, I didn't like the movie and wouldn't watch it again. If it had better actors and no singing, it probably would've been worth watching.
