The power and spectacle of cinema, the sound and the colour, is never more mesmerising or enthralling than with a musical. You can keep your big action movies or small indie dramas, they're good (sometimes) but once you've seen them, that's it, or it is for me. But when a truly original film (if such a thing still exists) combines with song, dance, lighting, script, storytelling and great performances, then you realise why movie making is such a special art form after all..
La La Land would have you believe that too, but it's open pandering to Hollywood and the American Dream (something intended to bring hope, when it can actually suggest the opposite) is the only issue I have with it.
The film is a beautiful painting. It feels both old and completely new; it references many great predecessors and yet has it's own style and charm, combining the very best of cinema. Ryan Gosling (possibly the best all round actor at the moment) and Emma Stone give superb performances, while the music and dance captivates, as it should in a musical.
