It just looks derpy. Its not the simple and easy to use old launcher with lots of customization, but it's designed to promote Realms and have fun images for kids just starting playing the game.
Get the old launcher here: https://minecraft.net/en-us/download/alternative download the second windows launcher.
Am I the only one who can't figure out how to use 1.8.9 OptiFine on the new launcher? It only gives me one option, 1.11.2 or 1.11.2
