Do you like anything? I don't recall ever reading you liking something.
I find the criticism of "the musical numbers felt sloppily stuck in" an odd choice since this was basically the Soundheim musical filmed by Tim Burton. That's the nature of a musical, random musical numbers to further the plot. There's a scene, and then there's a musical number in it, that's what _the_genre_is_.
For me the shades of gray nobodies really a hero is what made me like it more.
To debate, I'd say that Todd was the fallen hero in the way that MacBeth or Orpheus was that they where at one point noble, but a key point drove them mad or wicked and their nature fell. Burton's feel was awesome for the tone that this adapted play takes musically and it works.
It just seems that you went in not wanting to like it at all, and thus didn't.
I went in hoping I liked it better than the average musical, or at the very least I expected to like it in spite of being a musical.
And I like plenty of movies.
