While waiting to see “The King’s Speech” (which I highly recommend ) the movie previews included “Blue Valentine”.
The music for the preview is accompanied by a ukulele — a not–so-well tuned ukulele. But this can be excused because the protagonist is singing and strumming in a cold night outside a storefront.
You can view the preview and decide if it’s worth seeing. There are far too many tears in the preview to make me think it’s worth waiting for a happy ending to that ukulele song.
