Do producers think audiences are stupid? Do they really think that we won't realise we are being short-changed when they get together a couple of veteran actors (James Ellis and Michael Smiley) and a famous comic (Ed Byrne), plonk them on stage in a script that is no more than a series of gags and pass it off as a play? This tale of three generations of one family who have worked on Northern Ireland's buses is intermittently funny, vaguely heart-warming and almost completely mind-numbing in its predictability.
The play is set, partly against the background of the Troubles, in a hospital ward where Rinty's father TJ has been in a long-term coma. The past, present, living and dead collide in a single room as the family's history is told through their life on the buses. Unfortunately, the awkward structure ensures that the show never gets out of first gear, and, while the two older actors cruise through the script, Byrne gets by on sheer charm alone. It is not a show you could hate, but it looks suspiciously like a piece of festival opportunism designed to get the crowds in.
