I thought it was OK, the best being when Tom Cruise almost gets vaporized, then it turned stupid, not that it wasn`t already right from the start. I like how this alien machine comes from the ground and everybody stands around like they are expecting this....Nobody says "What the hell is that?" and throughout the whole movie everyone acts like they expect this alien attack. You would think at least one person would say "What the hell is going on??" or "What the hell is that?" but noooooooo, they all look up in the sky and see all this weird lightning and weird clouds and alien machines zapping them and none of them question it.."Oh it`s alien attacking us. Oh this is unfortunate, let us run away."
After the the opening bit where the first machine rose from beneath the street I thought it went downhill quickly. The whole bit with Tim Robbins in the basement was just stupid and unnecessary, and that's leaving out the casting of Tim Robbins. My complaints were mainly those aliens were so dumb: advanced as they were they didn't have infrared imaging technology, and they buried their machines here on earth, freezing the technology in place.
