A great concept... but lacking in execution (once again). The idea was that aliens had taken over the Earth for 1000 years already (year is 3000AD) but they've brainwashed the humans so that they've forgotten their past. The movie we ended up with doesn't explain this clearly enough, and it's completely different to what you'll expect. You expect a great deal of planning and an ingenious plot to overthrow these aliens but what you get is much more 'local' and disappointing. I find it hard to believe that during this whole time, having the humans in captivity, the aliens did not bother learning or at least finding some way to communicate with them, instead thinking they were just savages or animals with no real intelligence. Furthermore, in the human's revolution, somehow, they managed to learn how to control advanced technology (considering how degraded they are supposed to be) such as flying jets in a short period of time. Apparently, they've learnt how to fly them in a flight simulator, but you have to wonder, how the hell is it supplied with electricity? How the hell does the main character learn how to work the nuclear bomb? Even considering that he's got alien information, alien technology is supposed to be way more advanced so they won't cover it anyway.
Speaking of advance, if they are so advanced, how come 1000 year old planes (which somehow still functions perfectly, with the humans able to do complex aerial feats) managed to destroy those alien vessels?? And consider that the alien vessels had that 1000 years to advance even further, it boggles the mind. I found the acting to be terrible too, especially Barry Pepper's performance as the main character, for some reason, I just can't stand that character, he's annoying, rash and doesn't seem like the intelligent type to pull what he does off. I also have to say that the one bomb that destroys a whole planet to be poorly explained and harder to comprehend. The whole movie was boring, and it was a chore just sitting through it. None of the scenes were truly exciting or worthy of the mind. Seeing the cities in half ruins, you'd think that in 1000 years, it would have eroded way more, but nup, most of the structures are still perfect. It's these little (well, maybe not so little) things that ruin the movie a lot. If the characters of the movie had any sense, the so called 'revolution' could have been stopped ages ago. Put simply, this is a pretty bad movie.
