At some point, a regular audience member of Flash Festival needs a show that lightens the mood completely, as the trauma of themed issue shows can take its toll no matter how good they are. So, step forward Oh Arthur , a combination of some of the best moments of comedy and setpieces perhaps yet seen on the Flash Festival. I might have to hark back to the exceptional Sell-By-Date in 2014 to find a more consistently funny offering. Arthur is a layabout, a generally useless creature, bringing nothing to the world. In his wake are the victims of his inability to even attempt life in a good way, so, here is his mother, his girlfriend, his best mate, and others, dealing with him and his horrible behaviour. So, what's to like about a show with a person with no endearing features. Oddly enough, the superb performance of Simon Roseman and the intricate scripting make him likeable, sort of, in a way we like David Brent, well a little. It makes the unlikeable likeable in a devilish way...
