Alita was one of the first manga I read. I still have the early print editions of the VIZ comics, which I collected in the 90s. Along with Shirow Masamune's Appleseed, Alita was my early introduction to manga and it's weird to think that I have been reading manga for this long. Back then, manga were 30 page issues of a comic book bought at the comic store and not a hundred page volume of a soft cover graphic novel bought at Barnes and Noble. A comic is a comic, and manga is a comic. I still read lots of comics, but I buy them at Barnes and Noble.
Looking over my early manga reading I find that I was into sci-fi worlds. Now, I'm into shojo, moe girls, but still find myself reading sci-fi manga. Pluto, Saturn Apartments, 7 Billion Needles are all on my reading list and they are sci-fi. I can't get enough moe girls, but it seems I can't get enough sci-fi. Thanks, manga!
Battle Angel Alita is still ongoing! I hear that it isn't that great and Thompson says so to an extent. I still have my long boxes of comics from the 90s. I should dig up those VIZ comics issues from back then. I can't remember where I stopped reading. Maybe, I should dig up the volumes of the books on Amazon....
