The movie reminded me of "Terminator" because of
1) All of the alien killers coming after the boy and his protector, like Arnold in the first movie, killing one person after the other until they get to him.
2) His human protector, like Reese, dying to protect him, saving him for some obscure future destiny as leader of his fellow exiles.
3) The running gun battle between him and the inhuman, virtually unstoppable killers who seem to have no purpose beyond killing him and all like him
4) The fortuitous arrival of "Number Six" just when all seemed lost (granted, it would have been better if she had said, "come with me if you want to live,")
5) The ending, with its "We have a mission to protect all mankind from domination by the monsters" ending.
Listing them all like that, though, I guess the same could apply to half a dozen other movies.
