This film evokes feelings similar to the wonderment in Jurassic Park and the epicness (not a word, but should be) of Lord of the Rings.

Finally CGI that doesn't make you think "oh, that part is CGI".  The world is believable... it sucks you in and never spits you back out.

The story drags a litlte at first and the plot is far from life changing, but it holds your attention the entire 2 hours and 40 minutes by bouncing between the two sides with well developed characters (and being facinated with seeing even the most trivial stuff in 3D).

This was my first 3D movie, and although it was a great experience (this film is perfect for IMAX and 3D due to the sweeping landscape shots and sky-high locales), 3D technology still has a ways to go before it becomes ubiquitous.  Took about half the movie for me to adjust to it. 

Great cinemtography in the high action scenes.  Lots of stuff going on but I never felt overwhelemd or lost.  Good use of slow-mo helps.

In conclusion, I give it a 4/5.  Though the story is kinda shallow, the experience is an amazing one worthy of all the hype.
