Little exhausting, too much CGI, not much story... little robots are REALLY annoying, and their voices irritate me... you know the boy Sam, wasn't dead, you know Optimus Prime wasn't dead... left feeling... "eehhh?"
Didn't love or hate it, wouldn't see it again, or buy it... only interesting part was when the "old timer" was awoken and then you got some "STORY LINE"... maybe "3" will be better. Violence gets a little annoying, and tiring.
As for the IMAX experience... theater was TOO hot, but movie, sound and "big screen" experience are great! (15.00 is a little steep)
