I have been leary of the actual worthiness of 3D technology until I saw this movie. It by far surpassed my expectations. The 3D effects were amazing immersing you into the movie. The story is very well paced you will not get bored. It does not seem like almost 3 hours long at all. I thought they gave just enough background information to understand the story without lingering on unnecessary backlines. I purposely tried not to watch all of the trailers and read reviews for this movie before I saw it so I went in unbiased not even really knowing what the story was about. If you are planning on seeing this movie. A MUST see in 3D at the IMAX. The extra couple of bucks is money well spent!
