As I was watching the movie, I realized the same thing. I came up with a possibility.
Yeah, long run but then sat down with a friend, who was reading? I kept waiting for the pollen issue to come up though. I really thought that there would be something. My prediction as I suggested was that they had seasonal allergies and were on a prescription allergy medicine that blocked the histamines. But to just never even address it???
And the speaking tube? WHY did the old woman even mention that?? Besides to set it up for later.
It would be like dialoge going:
"Howdy stranger! Come on into my house, it's red, has yellow wallpaper, 3 bedrooms, 2 baths and I have a mole on my left ass cheek, just in case you wanted to shockingly discover it's me boing your wife later tonight."
Oh, and what about when they went to the unfriendly house
[spoiler]and the guy poked the gun out, shot the two kids, and they hovered over the kids, moaning and sad. WHY did the guy just shoot the kids??? It's not like they tried to protect themselves at all. They just stood in front of the gun themselves but nope, guess it was just the kids. [/spoiler]
The other thing I was sort of hoping was the "twist" was that
[spoiler]The trees were attacking aggression, not just groups of people. That could've been something interesting-- they meditate, calm themselves, and walk through the scary rustling grass unharmed. It even set that up!! The woman reading the book in the beginning was reading a murder mystery and her friend wasn't. And the woman reading the book died and the other woman didn't. And then in the end, they weren't scared at all as they walked across the field, so it fit. It would've been cheesy and hippie, but it would've at least been
something! [/spoiler]
Spoiler Alert[spoiler]When they were driving along in the jeep, and all of a sudden those guys were hanging from the posts, that startled me. But then the scared chick in the backseat ruined the scene.[/spoiler]
Yeah, I jumped at that too.
