We know nothing about the couple before the baby arrives, we know nothing about anyone else in the town etc. I don't mind it at all but if someone who knew nothing about superman watched it they may be a bit confused, of course anyone who wants to watch it likely knows the story of Superman so it's not a big deal. I liked the movie, the kid was creepy as hell and the gore didn't seem to go over the top considering what the kid was capable of. It's funny I've heard people complain about how the movie treated women, it's as if his "Dad" and "Uncle" got off scot-free lol.
