A river rises up to protest the attempt by a South American dictator  and his norteamericano architect to channel it. Or so we're told. We don't actually see the Rio Negro in Milcha Sanchez-Scott's  play--instead, we see a lot of actors making fancy speeches. Granted, it would be difficult to put a flooding river--or the  jungle that's being cleared to make room for El Dorado's gleaming new capital--on stage. Perhaps recognizing the futility of being  literal, the creators of "El Dorado" have gone abstract in the extreme. Loy Arcenas' set suggests the modern architecture of the new city.  But we don't see many of the trees, let alone the forest, until the  final scene, when a single shaft of green light represents an entire watershed--or even all of nature. Sanchez-Scott's characters are largely abstractions too--symbols and stereotypes. In Sanchez-Scott's earlier play "Roosters," her lyrical gifts transmuted the stereotypes into archetypes fairly well. That doesn't happen here. Beastly, shallow President Bustamante (Julian Gamble) has married  into El Dorado's ruling clan, the Mejias. He probably keeps his job only because the people love his glamorous wife, Inez (Joan   Stuart-Morris). In one scene, we hear the multitudes chanting Inez's name, followed by  a supposedly heartbreaking speech by Inez from her balcony. It's too bad she doesn't sing "Don't Cry for Me, El Dorado." But this is no musical, and "El Dorado" isn't about Inez as much as it's  about her two tiresome children. From her first marriage to an Indian politician, there is a troubled young man named Nestor (Michael Cerveris)--the play's least predictable but also least credible character. Half the time, he dresses all the way down to an aboriginal look, speaks incantations and rails about the doom in store for his country. The rest of the time, he dresses up for his role as a torturer for his stepfather; he has even earned the nickname "The Butcher." He puts the screws to a nun from Wisconsin (Karen Landry) who has  been accused of planting a bomb, then he decides to run away with her  into the jungle. His split personality is no secret, and it's hard to believe his stepfather continues to employ him as his henchman. Inez's other offspring, a daughter by Bustamante, is innocent Sonsita (Christine Avila), who has just returned from convent school in  Britain only to learn that she is regarded as marital fodder for a greasy politician. Sonsita and actress Avila--who appears a bit too mature for a  convent girl--are trapped by the writer's butterfly imagery as much  as by her parents' matrimonial plans. She counts butterflies, strokes them, wails over them when they're missing, and finally envisions herself as one. It would probably  work better on the page than on the stage, where you keep squinting in an effort to see if the little critters are actually there. The other characters display few signs of independent life, and director Peter Brosius' cast isn't much help. True, it's notable that Julio, the presidential palace factotum, is played by George Ede,  who seems to have wandered in from a British tour group. But this seems  to be a casting mistake rather than a commentary on the character. Or take David Hayward, who plays the American architect. The character is apparently supposed to project a great charisma; Inez and Sonsita  are attracted to him, and he represents Western faith in the   technocratic future. But Hayward just doesn't have that kind of magnetism. As a result, Sanchez-Scott's already lopsided arguments lean even farther away from the architect's point of view. The play is loaded to make political points, all of which add up to nothing very profound: Don't mess with Mother Nature, and watch out  for dictators who kill nuns. It's curious that Sanchez-Scott doesn't overtly mention global warming, which may be the most long-lasting result of Amazonian deforestation. Maybe she thought it would make the play   too obvious. Yet "El Dorado," despite atmospheric intimations of mystery (lighting, Peter Maradudin; sound, Michael Roth) is already too obvious. It  lacks the skillful characterizations and the startling visual imagery that might transform it into the spiritual experience that's apparently intended.
