A.I. had about 15 false endings, each of them sucked. My friend and I could barely contain our laughter when the "alien-looking robots from the future" came and dug out the kid and gave him his mom back. And the teddy bear climbing onto the bed at the end... it's just this sentimental crap that Spielberg does that annoys me.

WotW was unrealistic in my opinion. Many scenes would not have played out in real life the way they were portrayed in the movie. I mean, the first time the tripod comes out of the ground, everyone's just standing around, even as it's knocking over cars and buildings. I still don't understand why the main character doesn't shout out his window at everyone: "Replace the [electrical thingie] in your car, it'll run then!" I mean, I know most people wouldn't know how to fix that, but at least start spreading the knowledge.

The movie was original in the way it only followed a single person and not the government, but then later on, when the family reached the "crazy guy" house, it fell to complete shit. I mean, why the fuck did he have to kill the guy in cold blood? And it was goofy why he said, "close your eyes" when he went into the other room and closed the door anyway. Also, the lame "Jurassic Park kitchen raptor - esque" scene with a tripod worm camera lasted way too long and wasn't tense at all.

When he blew up the tripod with a grenade, the "basket of humans" looked like a low-budget TV movie set (as it was only close-up shots, and the set barely moved, even though it's on a giant walking machine).

The movie had a rushed ending. Having Morgan Freeman hired to narrate the beginning and ending was cheesy "as soon as the creatures breathed our air and ate our food, they were dooooomed."

Again, sentimental crap that Spielberg has to throw in every movie (the son magically survives).

I mean, it's the same thing dragged out... they're in the water... they're still in the water.... now they're yelling... they're still in the water... still in the water... still in the water.... credits rolling... wanting hours of life back...

While you could say that nothing in the movie was scientifically unfeasible, the way the aliens invaded Earth make the whole situation an impossibility. Burying machines for God knows how long in anticipation of later invading the planet and then terraforming it implies that the aliens do this sort of thing with some regularity. The idea that these aliens could invade other planets like this and never encounter a deadly micro-organism is highly unlikely. The idea that they also planted the machines on a dead planet (without micro-organisms) in the hopes that there would maybe be life there someday is also unlikely, seeing as how it's not going to be a guaranteed return.

It's that the movie didn't follow the book enough that makes it stupid. I don't know why the aliens couldn't have come from Mars. While we know plenty about Mars's surface, the possibility of there being a civilization living beneath it isn't entirely impossible. The book had already posited the idea that Mars could no longer sustain life. Is it really that unreasonable to present newspaper articles mentioning unusual activity on Mars as in the book?

An intelligent species invading another planet where there is a risk of dying from bacterium has to be presented as a desperate measure in order to remain plausible. That the machines were buried beneath the surface implies that the aliens aren't desperate, and that they have plenty of time to wait.
