The growth hormone treatment is gone through in detail and the early days of uncertainty at his Catalan home while the club dithered over whether to invest in such a risky and potentially expensive prospect, but this is all dull and basically well known. There's very little in the film you don't already know, if you like football and have spent some of the last ten years awake. The goals and the technique look marvellous on the big screen, but Iglesia keeps cutting back to his own biopic fragments, insisting on their relevance. There is no grit here. One of the journalists admits that Messi is an appallingly dull subject to interview - coming out with a string of platitudes - but that is basically what the film ends up being, along with some product placement for Barça's global brand.
Team mates Javier Mascherano and Gerard Piqué reveal precious little. Even when his tax affairs are mentioned, it's passed off with little more than a shrug. Leo himself doesn't participate, nor do his close family or ex-manager Pep Guardiola - another smart move. Some of the participants seem to be embarrassed by the endless lauding of the subject. One journalist even has the gall to suggest Pelé was a better player. Sadly, rather than delivering the riveting portrait of a Senna or a Zidane, Iglesia's Messi is a bungling hagiography lacking the deft touch and speed of its subject.
