So, like most of you, I've been watching Dr. Horrible. One thing I'm curious about is the last five minutes (from 12 minutes) in episode three. By now, it's probably off-line, but it's the part where he starts to sing his long final song, the one that mutates several times. Specifically, the high point at 12:53 (walking into the board room) makes me curious.
That scene was really cool.
I've written a few essays in this space, but I keep deleting them. It's very hard to talk about "cool", especially since most people think of kung-fu fights, explosions, and giant robots. The kind of quiet, cold, long-term cool you get from the last scene of Dr. Horrible is unusual.
There are only a few things I can work out for sure. One is music: without the music, the scene is much weaker. Actually, the music is most of the cool. The images punch it up and focus it.
But I was thinking: imagine a Dr. Horrible Puzzle Game. Pretty stereotypical third-person action-puzzle game starring Dr. Horrible, except that the cut-scenes are all at that level of cool. Doesn't have to be coherent: just kind of a "rock opera" interspersed with levels of puzzles. A bit like Portal, perhaps.
Don't you think that would be fun?
