[Ghoulish Delight]

I have misgivings about any movie that's been through as many hands as this one has. Writers, directors, actors. Eventually, someone's gotta feel like they've sunk too much money and they just put out whatever they can, whether it's good or not.

As for your concerns,

Spoiler:

To quote Mallrats, It's impossible, Lois could never have Superman's baby. Do you think her fallopian tubes could handle the sperm? I guarantee you he blows a load like a shotgun right through her back. What about her womb? Do you think it's strong enough to carry her child? He's an alien, for Christ sake. His Kyrptonian biological makeup is enhanced by earth's yellow sun. If Lois gets a tan the kid could kick right through her stomach. Only someone like Wonder Woman has a strong enough uterus to carry his kid. The only way he could bang regular chicks is with a kryptonite condom. And that would kill him.
