Any resemblence to an Imax DVD is strictly an accident. I missed it at the theater, it must have been impressive in 3D. But the DVD version comes across as a Speed Channel 24/7 of Nascar. If the DVD had been in 3D, OK. The sound is unbalanced. Keifer Sutherland is faint in the center channel so you increase the volume. Then the surrounds lite up and blow away the neighbours. I hope they redo it in 3D with a little less emphasis on the engines, please.
