It's simple. It's a very good movie. Not fantastic but wery good. The plot is not really new. A guy who gambles with money that doesn't belong to him and looses it to the mob. To survive he has to achieve an impossible task. Retrieve the money in 7 days and to organize a U2 concert. His probable executioner, being a big U2 fan, helps him in this task. A new uncommon friendship? You feel nostalgia, drama, humor, love etc. all over the scenes and places. Cinematography is nice, music fantastic, the characters, belonging to different worlds, make it very short-wile listening to them... I had a good time, time passed, the finale as U2 fan just fantastic.
