Catriona Knox

The platter of characters here are, at best, well-acted and have the right foundations to be spun into entertaining sketches. However, the dialogue doesn’t pack enough punch and the material quickly grates; that doesn’t deter Knox, who even returns to the same insubstantial characters later on. It seems a waste of the sparkle that this young lady clearly has.
