I can't believe that ANYone liked this horrible, lame acted, poorly scripted, goat's unwashed butt sucking film!
People have different opinions. Get over it.
It was the unrealistic reactions [read: poorly written plot points] of the characters.
Care to cite some examples?
"Let's fight 'em off with fire torches!" [enter gas grill explosions we could see coming a mile away]
What gas grill explosions? What happened is a guy kicked over a bucket of lighter fluid. And the movie actually acknowledged
afterwards that in hindsight, "that torch idea didn't work too well."
Or how about the crazy lady demanding the boy for "expiation" when she reaaaaally hated the lead [boy's father] but especially the leading lady.
I don't see a problem with this. For starters, even you admit Mrs. Carmody is crazy. Therefore her motives make sense to her, and only her.
what you're saying is, if Mrs. Carmody hated David, she should've tried to throw him
to the monsters, and not Billy. But I guess she figured since the blood of a "sinner" (i.e. Private Jessup) didn't work, maybe the blood of an innocent would
Oh, and the ending. When the kid said he didn't want the monsters to get him, I'm sure he didn't mean, "Hey, I'd rather you just popped a cap in me instead, dad." No, he wanted to live. The "twist" made no sense, since dad had invested so much in keeping his kid alive. They weren't out of options. [Yes, walking was still possible, though not preferable. Nor had they sat there for days or anything. They weren't starving to mdeath. The car stopped and everyone just decided, OK, that's enough for me.]
Now this I'll agree with. The decision to do a murder-suicide pact came too soon, although in David's defense we don't know how long they'd been driving.
You ruin the ending, you ruin the film. Period.
That's entirely subjective. Plenty of otherwise good movies have lousy endings. And likewise, many good ones have bad beginnings as well.
