If you think that asses can't sing and the HIV virus could not be the grand diva of a film musical, you've not seen this film!These absurdities come to live in song and dance, as do other virusses, visitors of a gay bathhouse, and a bunch of wildlife animals accused of spreading diseases. The story enjoyably deals with a sexologist/explorer, Richard, who's been around since the 19th century, and his current obsession of creating a museum display on Patient Zero, the flight attendant who supposedly brought AIDS from Africa. The ghost of the deceased Zero decides to help and rid him of his prejudices. The film touches on themes such as early AIDS media response and hype, to more profound ones such dealing with loneliness and death. The songs help telling the story, rather than putting it on hold, and despite the incredibility of the plot, the main characters are perfectly believable. Zero and Richard fall in love, in fact the latter is the only one who can see and touch his temporarily-returned-to- flesh subject - a clever plot device; since they are both anachronisms. In the end they must part, as Zero returns to existentional void. Shades of romantic literature and ballet here. But both men are wiser, Zero for putting an end to a ridiculous theory, and the professor for being rid of his blame-fetishizing ideas. Underestimated and very entertaining!
