it's hilarious that this thread was bumped again this year; it made slightly more sense last year since In the Heights really was his last "hit" before Hamilton, I'd say. obviously he's done other work but these are his big things so far. I don't think he'll be a two-hit wonder either (and won't be surprised if he wins an Oscar for Moana). I fully expect another big show several years from now.
