[Movie] Predators

I think that most people who are fans of the Predator mythos, or whatever you want to call it, will end up asking 'why?' instead of actually downright hating the movie.

It has nothing to do with looking like it's a bad movie, I love me some Adrien Brody, but why are the predators bringing humans to their planet now? What happened to the 'rights of passage' that it was for a young predator to travel to a far off world to either prove that he was fit enough to survive/kill? Even with the idea that they are 'testing' a new breed of predator, wouldn't the same idea fit? Send IT to another planet to see how it survives?

I'm hoping that in some way, shape, or form they answer these questions in the movie. If they don't then it would seem unnecessary for this movie to exist.

Jam it back in, in the dark.
