No desire for this.
I really enjoyed Planetary for what it was, although I think it's become a little overrated in the intervening years. Anyway, it was pure Ellis, and certainly the smartest (if not emotionally truest) thing he's done outside of Transmet.
But what made the book great wasn't any character in particular. It wasn't the Drummer, it wasn't Jakita, it wasn't even Snow. Most of those characters were, as mentioned, thinly veiled pastiches of other characters.
Two things primarily made it great; 1. It was an exploration and critique of pop culture phenomena. It had depth and it had purpose, every issue. 2. There was a TONE, a desire for big ideas and forward thinking, that classic Ellis romantic sci-fi.
Paul Cornell had it right, conceptually, creating his own characters that very much FELT like Ellis characters, but with which he had free reign. Part of the wonder of those characters was precisely that you didn't know them very well -- they were unpredictable, they were enigmatic, there was a lot to learn.
Unfortunately it didn't come off -- Paul Cornell isn't Warren Ellis, and he never will be, and his downfall was trying to write like Warren Ellis instead of trying to write like Paul Cornell. But I think the spirit of what he was trying to do, what he was trying to capture, was good, even if his particular execution didn't match up.
