La La Land
You've probably seen the advance publicity - Gosling & Stone in a hymn of praise to the MGM musical, tender and witty and bound to win every award going. And that isn't too far from the truth.
Stone has the perfect light touch to convince, and can sing and dance more than adequately. Gosling is a bit uptight, and not as good at either singing or dancing, but he isn't bad, and definitely pulls it off. While there is no doubt that the film is a hymn of praise to the MGM musical (An American In Paris especially, and massive doses of the stupendous Young Girls of Rochefort) it is more than that too. Like the fight that Gosling tells us goes in within jazz, there is a tension within this film as nostalgia and anti-nostalgia fight it out, the pure and principled but staid and unchanging v fusion and modern techniques - that can sometimes end up as utter wank. The 'golden age' jazz Gosling listens to may well be the height of the genre's history, but it is still dead and gone, those who want to simply relive it will end up locked away in underground caverns missing what goes on in the rest of the world.
When I first came out i thought that Stone had been superb but Gosling a little underwhelming, his face being too monotone. In the almost final scene he displays such a light touch, an elegance and grace that had been missing from the rest of the movie, and I thought it was a real shame he hadn't let any of that into the earlier scenes. But, of course, with a bit of thought, he had played it exactly right. That lightness was precisely what he was missing, that was his (characters) problem. So, well played that man.
Minor criticisms- sometimes the music drowned out the lyrics, which should never happen in a musical, and the 'modern' jazz was mid-eighties synthy crap, which everyone now knows is awful, actual modern stuff wouldn't have fitted with the theme tho.
Despite those quibbles - A cracker, go and see it.
