I love In The Heights, but the prospect of a movie is at least 12 months away, more likely closer to 24 months. It's had a very successful run, has generated a tour, and is slated for filming. By any conceivable standard, it's an immense success. I, for one, don't mourn shows that close after successful runs. While I don't wish the loss of work on anyone, in or out of the theater, Broadway needs new shows to thrive. I think far too many shows outlive their use, and Broadway would be better served, at least artistically, with more new productions.
