Yep, lots of hype, but the movie exceeded it. There is no visible CGI, there is just movie. The story is great, the characters are great. The evil corporate and military guys are a bit over the top, but that still works. And the 3D/iMax is great but it can give you serious motion sickness if you are prone to that.
I'm going again and I had to drive from Sarasota to Tampa.
