Lopsided and a bit misdirected, but overall entertaining and informative. The Botany of Desire is obviously trying to entice people into watching a film about something that sends most people to sleep: agriculture and botany. Not a sexy subject in the least, it tries its best (most obviously, in its title) to make its subject appealing to a mass audience. As such, it gets a bit anthro-centric and pop-culturey... complete with gimmicky title cards and simplified narrative structures.
Underneath all the polish though, is an informative and well-thought piece of educational film, notably the beautifully neutral section on Marijuana and the riveting socio-economic history of the Tulip. The genetic-food focus of the Potato, and the somewhat mythologized history of the Apple, the bookends of the film, fall short. Overall, it succeeds as education but looks a bit ridiculous as it tries to pantomime entertainment.
