From the Movie Snob:

Tropical Rainforest. (D) While home for Thanksgiving in Little Rock, Arkansas, I visited Arkansas' only IMAX theater and saw this science documentary. According to the Internet Movie Database, it was made in 1992, which was apparently before the makers of IMAX documentaries thought their products needed to be interesting. The film consisted mostly of long shots of trees and other vegetation, with wildlife and human scientists making only sporadic appearances. There was a strong don't-destroy-the-rainforests message too, which was fine but didn't make the film any more interesting. My sister, who is a biology Ph.D. student, gave it a B-, but I have to respectfully dissent from her opinion.
