Absolutely game changing from a visual point of view (3D version). Must be seen, and must be seen on big screen. 3D aspect very powerful and engaging. Not cheesy like the old days. Still a bit overdone in a few places, but generally awesome.
The story, plot, character development, acting, etc. are all good. Not great, not bad. Good, at least for an action movie. Much of it is very predictable and contrived, but the execution is good enough that it's still tolerable, and even when it isn't just sit back and look at it. Wow.
The editing could have been a little tighter. I did become aware of how long it is a couple of times and wanted things to get moving.
