There is certainly nothing wrong with simplicity. This minimal poster for upcoming Emma Stone and Ryan Gosling musical, La La Land, still offers plenty of information. The posh clothing indicates a swanky night out, the stage door sign indicated that this is likely the two performing. Not sure what the cool blue tint is indicative of, but the text helpfully offers that the film is from, Damien Chazelle, the director of Whiplash.
The musical premieres in Venice and Toronto in the coming weeks before getting a limited theatrical release in December.
