Dregs

Max Dickins and Mark Smith present an hour which thrives on its unpredictability, offering character-based sketches while maintaining a constant audience engagement. The show takes slightly too long to gather momentum, after an awkward start, and would benefit from less shouting on occasion. However, the pair emerge as endearing and self-aware with a good deal of promising material.
