The most perfect ending. *spoilers*
The ending is the most important part of any film. Very few films have truly, truly perfect endings. Mysterious Skin comes to mind. So does Pieces of April. These films have perfect endings.
I can't get over Sing Street's ending, though. The last shot of the film is of Conor staring happily and intensely into the unknown. The whole scene plays out like a fantasy, and I love it. I love that we never find out what happens to Conor and Raphina. For all we know, the boat flipped over ten seconds after roll credits, and they both drowned. Or perhaps when they made it to London, they grew to hate each other. Perhaps they never found fame. Perhaps a week later, they got scared and moved back to Ireland. Or perhaps they both found major success and got away from their painful lives in Dublin.
The beauty of the ending is that it doesn't matter what happens. The endgame doesn't matter at all. All that matters is they're taking a chance. They're setting off together with hope for a better future. This is one of the most hopeful films I've ever seen, and it's easily either my first or second favorite movie of all time. (It switches with Mysterious Skin occasionally).
I don't feel enough for you to cry.
Oh well.
