Mostly, I'm with Bill. I think the article he quotes is a little overexcited, but in general, damn good movie despite Alan Moore's petulant foot-stamping. Also, Best 1812 Overture Evar.
I am somewhat bemused, and certainly quite surprised, to discover that Edgar A. Poe wrote sci-fi. I mean, ok, 12-track high-speed railways and balloons that travel at hundreds of miles per hour, but still pretty cool.
