We began showing this film in its 4-D variant at a major nearby aquarium, where I work as an educator. I've personally seen it many times so far, and I have very little to complain about, aside from minor errors scientifically that ordinary guests would never pick up. The only complaint that I have is in the length--the film could be a bit more in-depth and involved than it is, and could thereby make it more deserving of the price we make people pay to see it. It certainly lays a surprisingly complex series of characters and details, its graphics and 4-D effects are employed masterfully, and its premise is still very creative nonetheless. In its eight months of showings, it seems to have made many riders--especially the younger ones--pretty happy with the experience.
