This isn't anything as coherent as a review of Heathers: The Musical, but I need to ramble about it.

I've seen a lot of musicals in my time. But I can't remember any that made me so impressed and so uncomfortable at the same time.

( Spoilers )

Overall, it was incredibly well put together. The cast was fantastic. The plot was lean and brisk. Every beat was true. Every reaction was earned. Every song was a punch of emotion. It's just about a note perfect example of a musical. The cool thing about adaptations is, they give you a chance to refine the essence of the original. I should have guessed, from the calibre of the songs, that it was co-written by one of the co-writers of Legally Blonde: The Musical. Not always easy to watch, but very worthwhile.
