Seth Caikowski has played sidekicks and leading men, dignified figures and cartoonish clowns. In Boulder's Dinner Theatre's The Full Monty, he got to display another aspect of his versatility as working-class Jerry, tough-minded and humorous, but emotionally vulnerable in his relationship with his young son and ex-wife. Since this is a musical about regular guys putting on a clumsy strip act, the dancing can't look too professional — but it should still be an audience-pleaser. Caikowski handled this contradiction with skill, athletically light on his feet without appearing dancer-trained. And he imbued the entire role with dignity and strength.
