From The Movie Snob:

Dolphins (C+). I visited my parents this weekend, and I wanted to take them to a movie. This IMAX feature was the only one that presented itself as a feasible candidate. It was decent, much better than the last one we attended, the snoozefest Tropical Rainforest. This one was, as you've probably guessed, about dolphins. It was about what you'd expect -- lots of footage of dolphins, some footage of scientists who are dolphin specialists, a warning about degradation of the dolphins' environment. Pierce Brosnan takes time out from playing James Bond to provide an appropriately serious-and-concerned-sounding narration, while Sting's cerebral musical stylings provide a lush sonic background. Plus, on Friday nights, you get a ticket, small popcorn, and coke for $5. Not a bad way to spend an hour and five bucks.
