Sadly, nobody saw the Dardennes' movie, so I'm hijacking this thread in the name of the ultimate kid-with-a-bike movie, Premium Rush.
What Haywire was to '90s direct-to-video action movies, Premium Rush is to '90s extreme sports movies, except ten times as fun. I honestly can't tell how much the filmmakers were taking it seriously and how much they were taking the piss, and frankly, I'm not sure which I would prefer.
The first and most important thing about the movie is that Joseph Gordon-Levitt's character hates brakes. HATES 'EM. We know this because he says so at least once every 90 seconds. His hatred of brakes is so potent that at one point it causes his estranged, ethnically-diverse girlfriend to rip the brakes off her own bike, blaming them rather than her decision-making for the accident she just got into. He also hates bikes with multiple gears, but manages to express this disdain through his lifestyle choices rather than talking about it all the damn time.
Somehow, though, brakes are not the main antagonist of the film. That honor goes to the movie's secret weapon, Michael Shannon, playing Ray Liotta if Ray Liotta were a mid-90s Gary Oldman character. You guys, Michael Shannon is SO GOOD in this movie. He goes over over-the-top's top from beginning to end. There is no scenery that is safe from his hungry jaws.
I'll try not to spoil too much in the way of plot (it really doesn't matter), but I do have to describe one scene that exemplifies why I loved this movie. JGL and his still-somewhat-estranged girlfriend with a distracting accent are trapped in a police impound garage, hiding behind all the impounded bikes. JGL's bike is smashed to bits, Michael Shannon is hot on his trail, and goddammit, he still has a package to deliver. Suddenly, he spots a beat-up old BMX bike hanging up on the wall. He says something along the lines of, "I can totally shred on that." (That's not the exact line, but it's how I remembered it.) The Raconteurs' "Salute Your Solution" starts blasting on the soundtrack, and next thing you know he's bike-parkouring all over that garage. The greatest poets who ever lived could not adequately describe how happy this scene made me.
To sum it up,
it's a masterpiece.
