Its just violent. The plot is cool. They grab bunch of bad ass HS kids drop them off an island and the sole survivor gets to live and leave the island. No friends and trust no one type shit. As the hours go bye, certain parts of the island is a no-trepass area (lasers and shit guarding it), which forces these teens to fight and kill in a more confined space. The acting suckssssss but its just something fun to watch. Its just a crucial way to deal with bad ass kids...wish we can do this too.
But part 2 is a no no.
