Boring, Moronic Explanation

I am just trying to get passed the first 22 minutes. The good reviews are making me stick with it.

Perhaps the explanation of her condition could have been done a bit better. But if anyone here is "unimaginative imbecile writer", then its the original poster.

What you hated was precisely what I liked very much.*

A lot of people have relatively little interest in supernatural horror because it couldn't actually happen. Give the same story a sci-fi rationale, and it immediately becomes more engaging.

I do think this is more a sci-fi movie than a horror movie. And there's a brand of sci-fi where you make the science just credible enough to carry the sort of story you want to tell (in this case, what it would take for an immortal to decide to fall in love and become mortal thereby). It's called a "hand-wave" by sf writers.

I would say the science here is actually more plausible than the explanation for the three-year life-span of the replicants in Blade Runner, which uses invented (but very plausible-sounding) jargon. Embryonic stem cells have just enough mystery left to make them a workable hand-wave.

*I do agree with the criticism that the way the explanation is delivered is relatively weak. If at all possible, you want to avoid any scene where one character explains it all to another. A better screenplay would have had Evan finding clues and evidence that allowed him to put a good chunk of the story together himself, with us in the audience experiencing the same "aha!" moment as he does.

If the girl had been doing animal studies that attempted to replicate her own condition, and Evan had found those ... e.g., at some point he finds out that pregnancy alters the fate of injected stem cells; cut to his flashback memory of the girl tossing away the condom.

Prepare your minds for a new scale of physical, scientific values, gentlemen.
