This music-biz romp – concerning a Welsh chancer's attempts to push Libertines-like ladrockers the Premature Congratulations around Soho – hopes bushy-tailed enthusiasm can usher us past a shortfall of jokes, and displays an abiding cluelessness about developing its source (writer-star Jonny Owen's well-regarded web series) beyond middling sitcom territory. Cameos from TV faces and a summery visual sheen provide further distractions from the script's fundamental issues of cred: you just don't believe Owen's hapless protagonist would get as far as he does. Hard to dislike entirely, but that initial pep wears off – and it's sad that any project should now be wasting Vicky McClure in the tagalong girlfriend role.
