Saw this movie last night, (3 times the charm! Our first two attempts failed since the IMAX shows were sold out each time we tried to buy tickets--now I see why!)
Not only were the 3D special effects totally cool, the acting was solid, the action riveting, and the messages strong.
We completely loved this movie--I still can't get over how awesome the 3D IMAX Experience was added to a darn good movie!
