Here endeth “The Valentine Trilogy,” which follows a single character–often, but not exclusively, known as Elliot Dodge–through adventures in three pop genres. The first installment was a western; the second, a samurai tale; and this one is a superhero saga set in 1930s Chicago. Think Road to Perdition meets Stupendous Man from Calvin and Hobbes. Valentine Victorious is longer than it needs to be, and neither its pseudoscience nor its pseudoplot makes much pseudosense. But Dennis Watkins’s staging for the House Theatre of Chicago is full of generous fun, bright energy, good music–and great, cheap coups de theatre: a nuclear explosion, for instance, realized by means of green umbrellas. Writer-star Nathan Allen cavorts like a kid before his bedroom mirror. Through 3/11: Thu-Sat 8 PM, Sun 7 PM, Viaduct Theater, 3111 N. Western, 773-251-2195, $10-$19, industry nights Thu and Sun.
