Thought the 3d effects were exceptional but the storyline was ill conceived. Sounded like another President Obama apology tour. I'm a little sick of the high brow Hollywood crowd slipping in their opinion of how terrible we are as American to the rest of the poor oppressed peaceful inhabitants of the planet while making a freakin' 800 million dollar movie. But I ramble (much as Cameron did on this flick. 2:40 run time was too long. If he'd condensed this to 1:50 or so he might would have salvaged the story and everyone's patience. Good action sequences with amusing 3d make it worth a watch on Matinee prices.
