I have never seen Ghost in a shell, but I don't see a matrix feel so much. It has a following in Circvs Maximvs that is getting a fight club vibe from it though.
Oh man, if it WAS like that, it would be totally awesome!
I have a limited experience with this genre of movies, but I would say it's something closer to Hackers than the Matrix or GitSAC.
And the show is okay. I've seen all five episodes so far and I'm still not really sure what to think, though on the plus side there were a couple of points where I was caught completely off guard, so it isn't as predictable as so many other TV shows are.
