I will credit Romero that he basically tried to adapt the first game and included a lot of the original game's monsters in it, but it was a bit of a clunky script. Like when I realized what they'd done with Chris and Jill, I was like...WTF is this ****?
Now, was the script better than what we ultimately ended up with and all the Mary Sue Alice BS? Fake Wesker, Fake Umbrella, cause the apocalypse, nonsensical idiocy? Yes. But on the other hand, I can see why it didn't pan out either. It probably would've been too expensive to make as well.
Having Chris and Jill be lovers, Chris is a civilian rancher, and has no idea Jill is a secret agent is f'n stupid, though. No disrespect Romero. It was stupid.
