What a waste *spoilers*
The first half was semi-interesting setup. Then, the entire second half of the movie was him demanding she tell him what's going on, and her refusing and freaking out like a terrified toddler.
The plot was weak and illogical. So the aliens impregnate them, leave them just long enough that everyone figures out what they are, then comes back for them? If they wanted to transform human women into their own species for companionship, why not just kidnap them and be done with it?
And the husband...could he have been any more ineffectual? I kept waiting for him to toss her over his shoulder, carry her ass out to the car, and take her into town to see a doctor whether she wanted to or not. But no, he just wallowed in his own angst and uselessness until it was too late.
I was glad to be rid of both of them.
Oh, and probing alien lights, really? They can travel halfway across the universe and completely transform biological specimens, but they still need a giant flashlight to find their way around? That's one alien-movie trope that should have been retired a long time ago.
