The problem is that the “who knows” response can be used to defend any and all stupid movie premises ever. Try it.
Creature from the black lagoon-scarry when I was a kid. In creature 3 the creature wears a suit.
Except it can’t.
Sure it can. How does it work? Who knows?
Name a premise that can’t be defended by “who knows”.
Sure it can.
“Is Verhoeven a hack, or just an idiot?”
Who knows?
“Is Carrot-Top the anti-Christ?”
Who knows?
“Are M. Night Shanana movies stupid, or just lazy?”
Who knows?
Oh. Basically both are supposed to be spoofs of the action genre. Last Action Hero spoofing the Schwartzeniger/Lethal Weapon/Die Hard type films and True Lies being a send-up of Bond-style spy films. Basically Harry Tasker lives this normal home life and goes off to work to become this ridiculous characterature of James Bond.
Okay, I just had a thought about Signs. We hear on the radio that people in a Middle Eastern town had found “a primitive way to fight” the aliens. Then we see that one of them is damaged by water from one of the little girl’s many glasses that she leaves all over the house.
Maybe it’s not the water – it’s little girl spit! You get enough little girls to spit on one of those ugly bastards and he’s down for the count! (And believe me, I’ve known some tantrum-throwing little girls that could do the job.)
(I can’t help wondering whether something in the nature of a gun might have worked, too.)
A water pistol, surely. 
You know, the logical extension of this (ways to fight monsters who are vulnerable to water) showed up in one of Jack Chalker’s Well World novels.
Basically, people peed at them.
I can just see a drunk bunch of guys coming out of a bar and exercising their public duty. Not as efficient as fire hoses, but more personal.
Um, I don’t feel like I had to exercise my intelligence particularly hard to notice the huge, gaping holes in the premise of the movie. I don’t think that noticing how poorly thought out the film was makes me smart. The holes in the movie were obvious. They were gaping. Small children have fallen into them and died. They’re the only man-made structure that can be seen from space!
Not that it saves the movie, but the prisoner plane was Cage’s only flight home.
What I’m thinking is that the two thread topics most likely to result in a flamefest are tipping and Signs. 
What about indoors versus outdoors cats?
How would you do it?
He pled guilty and was judged harshly due to his military skills. Besides, the long sentence isn’t part of the premise. What’s so strange about him being flown to his original prison on a plane used for transporting prisoners?
Unrealistic? Sure. Stupid? How?
Why wouldn’t one guy be able to steal ten cars in one night? Besides, weren’t there more than five of them? Besides, this isn’t part of the premise either.
Sure, but not part of the premise either.
I don’t remember anything about him being a pussy in the other hundred-odd dimensions.
I dont’ think it qualifies as a premise, really, but the movie “THe Green Mile” did not require a suspension of disbelief because of the mystical and magical aspects, it required a suspension of disbelief for this:
the fact that a the year is 1933 or something, it’s the Deep South, a posse of locals with guns has found a giant black man holding the dead and bloodied bodies of two tiny white female children and he makes it to prison???
Yeah, right. Sure. Trust me, “Speed” is more believable.
I’m a fan of Signs, as I’ve stated in other threads, a big fan–yet even I think the movie is an excellent argument for personal gun ownership.
Ah, it’s much worse than that. Remember that the Mariner makes a precarious living by diving to the bottom of the ocean and salvaging crap. He even takes the girl down on a pleasure expedition to see some ruined city. OK, but Mt. Everest, the only remaining dry land, is 29,035 feet high. Denver is famously one mile high. So the Mariner was apparently diving down 4+ miles to do his scavenging. Not hardly. Not even once. For 20 minutes. In 2060.
Of course, the mortician wasn’t necessary (I’m sure with all the other stuff the Marshal managed he could have stuffed some explosives in the coffin), and if you cut out Mother and Daughter you don’t need the flight attendant either!

This reminds me of some shitty Y2K distaster movie. The plot was that the hydroelectric plant would revert to 1900, and would freak out because it would think it hadn’t been filled with water yet.
Is it ever stated outright that the Dryland they reach is in fact Mount Everest, and that it is in fact the only remaining dry land? I mean, how would they know either for a fact?
