Can be confusing in some parts ( maybe it links to the previous versions of the movie) . 3d was good but could have been much better. I would have preferred watching it in 2d. Graphics was mind blowing. Story ok. Same old alien trying to invade the humanity logic and how USA saves the day again.
So you preety much know what the story is. Sorry for the spoiler. Overall its a good movie. Nothing extra ordinary though.
