Chris O'Dowd's semi-autobiographical sitcom is back for its long awaited second series tonight. The comedy follows 12 year old Martin Moone, who is trying to make his way through his childhood in small town Ireland in the late eighties - all with the help of his invisible friend Sean, played by O'Dowd. In tonight's first episode, Martin is appalled when his dad takes the family on holiday during the 1990 World Cup, so he tries to hitch-hike back to Boyle to watch a vital match on home turf. Ah, Italia '90.. this show is worth it alone for the warm dose of nostalgia you feel watching it.
