A good double bill of one act plays can be a bit of a rarity. It might consist of pieces with radically different themes by diverse writers who adopt varying tones forming an unsatisfactory pairing. Or it might just gel as a cohesive evening where each element benefits from the presence of the other and enhances the overall experience. Fortunately Generation Games, currently playing at the White Bear Theatre, falls into the latter category with both plays examining intergenerational gay relationships.
