At the end of the series, all Renae and I could say was, "Joss Whedon, you sadistic @#$%&?!"
We should've know that he'd kill off at least one of major characters before he was through.
That's what a lot of fans are saying. I'm seeing a funny (odd) parallel between fans (not you, I'm sure) who say "Joss is god" and people (again, not you) who say God is sadistic. There may be redemption in Joss Whedon's fictional world, but there actions/choices also always have consequences.
Major character was doomed from the moment in act II that Billy chose to pursue Horrible revenge rather than true love...but by that time, we viewers were caught up in his dorky evil charm and musical-ness and overlooking the fact that his bloggings were eerily similar to the records left by the Columbine and Virginia Tech shooters. We hear "musical" and think "Oh--
Sound of Music!
Mary Poppins"--but tragedy can also be set to music, only usually it's called "opera". Twisting genres since 1992--Joss Whedon, people!
