I'd have preferred for Cameron to direct it (because, when I first read Gunnm, Judgment Day and Aliens were already the best action movies ever) but it was not meant to be so I'll take what I can. I'm not a fan of Rodriguez but I did like the one graphic novel adaptation he made (Sin City), so there is hope. My only real problems with the trailer is that the 'verse is not as grimdark and cyberpunky as it should be and that a few key elements seem to have been adapted out (or kept for a sequel) including arch-nemesis and mad scientist extraordinaire Desty Nova (however, to be fair, he only properly appeared in the manga after the first few story arcs) . Also, it seems that Vector is now a stereotypical big bad crime boss instead of the more nuanced amoral bastard he was in the manga. Then again, that's just the trailer, and you should never trust a trailer.
I'm not the biggest fan of the Last Order sequel either (though I did like the first arc on Zalem (Tiphares) and I don't particularly dislike the idea of space faring immortal bloodsuckers, the whole ZOTT thing was an overly drawn-out tournament arc that was way to 'shonen' to my taste. The new prequel (well, mostly) Mars Chronicle is better in my opinion, but I still prefer the first series.
