Death comes to us all in the end, often in a slow, painful and undiginfied manner. Some people, faced with a terminal diagnosis, prefer to check out early, which is illegal in Britain (unless it is done unaided) but is allowed in some other countries. To do so is, of course, a horrifically enormous decision. 'Mayflies' tells one such story, but, as its title suggests, it also encourages us to reflect on the briefness of life, and how we might end up facing our own deaths when our youths seem barely to have passed. It's a warm and affectionate piece, avoiding over-sentimentality (though some is necessarily in order). It does choose to give us a character the severity of whose illness is mostly hidden from us in off-camera visits to the toilet; our protagonist still presents as very much alive throughout the drama, which allows him full mental responsibility, but which also makes his choice seem somewhat premature. Not much happens that isn't obviously telegraphed from the outset; but it's an intelligent dramatisation of the realities of death and the ways we might choose to face it.
