I was definitely underwhelmed - the movie starts off strong in terms of initial setting and effects, but falls apart more and more the further along it goes.
First its realizing that it's just androids - I get the budget limitations, but this isn't a non-human civilization like The Matrix hints at, it's just future brown people, acted by humans with green or blue screen wraps to be rotoscoped out later, all of whom live out standard human lives.
Second the movie frankly does nothing to establish why we should be rooting for the robots, given that the robots grenade a civilian (robot, but still one of their civilians) to get access to the apartment with the kid and immediately open up on a van full of human civilians at the checkpoint. We have no reason to believe their torture murder of Alison Janney's kid isn't legitimate either.
Third, the motivations of the Americans don't make sense - at some point, they suddenly don't care about the Creator, since if they get 'the child', they will know where the robots are to wipe them out? But I thought New Asia covered the entire Pacific Rim, including the fucking huge city in Thailand (?) with the robot factory? They don't have radar or maps in the future to know where they're at?
Fourth, the movie completely falls apart in the climax. Apparently all it took for the robots to win the war was have one single android make it past security at LAX to catch a regularly scheduled flight to The Disassemble Star since one grenade will blow up the entire base. Who knew. (Also one satchel charge on the outside of an apartment building sized tank will take those down too.)
I'd say it's worth a watch _once_ to admire what they were able to pull off with their budget, but nothing else holds up past the slightest of investigation.
