Fantastic - my husband and I really enjoyed - IMAX was wonderful- I had to keep myself from reaching out to touch the falling ash...... a few gaps in the story that I noticed but not that important ....I thought the 2 hrs and 40 mins went by fast but my two late teen/early 20's kids thought it went on forever - guess they are so used to 3D and video games that it wasn't as special to them. They did like the movie however.
