'La La Land' will let you know and get into thinking about the perspective of an artist. An artist knows fire within himself/herself and try to follow it without any sense of being judge by others. Fame and revolution doesn't come to every artist but it also never drives a true artist. That's what this movie is about. The last '8 minute sequence of how life would have been between them' was a piece of art and a dream sequence for a love story. That's what leaves ending even on a higher note and so to the movie. A true inspiration and tribute to all the artists in the world.
