I'm going to assume you just quoted my whole post without actually reading it:
It's not about realism, it's exactly what you said it was - suspension of disbelief.
Suspension of disbelief works when the movie world is consistent within itself, and I don't feel The Mist did that for me in terms of creature behavior and the Impossibly Silent Army.
If I had to describe the way I look at movies, I'd say I'm a flavor-oriented worldbuilder. Everything the movie provides to me adds another piece of information that helps me see the world the movie is trying to show me.
For me, the movie established itself not as something largely allegorical. The creatures in the mist were not a modern variant of the Grue, but simple animals that accidentally wandered into a world that wasn't their own.
For example, I loved the scenes with the mosquitoes and the Flying Things before they crashed into the mall. I immediately got the picture that the mosquitoes rested on natural clifffaces at night, and the Flying Things hunted them. Even when an unseen creature finished off the Biker's legs, it fit the picture of a creature that wandered by, smelled something good, and ate it.
You may disagree, but I
strongly feel the movie was asking me to make a huge jump from those previous creature experiences to Omg-Humans-Attack situations. Like I said in the original post, the non-terran animals turned from
creatures to
monsters, harming the movie for me.
As for the Christian lady... it would have been
must scarier and
more appealing if she wasn't firebreathing seconds after the Mist came down. Calm and almost reasonable, the viewer would have
almost been tempted by her sermons, much like the other people in the mall.
How interesting would it have been if the Christian Lady only went batshit at the very end, and it was one of her closest follower - that other redhead one that said "YOU MURDERED HER!" - was the one that stopped the fighting by knocking out the Christian Lady during the final conflict?
Finally, I agree that the very last one was picky, but I meant it as a joke. The second I saw it, my girlfriend leaned over and went "aren't they moving those folks into the mist again?"
I'd write more, but I have work to get ready for
