That the absolute best anime series I have ever encountered (and I've watched a fair amount) is a) not still being produced

Not as wildly popular as I think it should be c) i've only run across so few since it that are even fit to be mentioned in the same conversation.
What am I talking about ?
Ghost in the shell of course. Now, the movies are one thing and they're pretty decent, the second one being particularly beautiful,
but what really blows my mind is Stand Alone Complex 1, 2 is also very good if more disjointed and a little less artfully intellectual. Solid state society was good, but not as satisfyingly deep and labyrinthine as the 1st standalone complex and it wasn't a whole series/season.
Just in case someone asks I've watched many of what I think are widely considered the deepest/best series such as but not limited to:
ergo proxy (also very good and relatively deep, but not as satisfying intellectually and frankly it ended way too soon and abruptly this seems to be a trend with most anime series i've seen)
Death Note (fantastic, but not as forward looking at society/technology, still quite good i'd put this somewhere around number 2 in my list)
Evangelion (meh, it was ok, but not terribly deep imo)
Jin Roh (ok but again not that deep imo)
Planetes (Fantastic idea, much of this was brilliant sci-fi wise, but it fell back on too many stereotypes of anime in characterization)
Gantz (not bad, but as most have noted the ending was not so swift).
Cowboy Bebop (just could never get into this even though it seemed like it had a lot going for it, I'll try it again from the beginning this time I guess)
Appleseed both of them (can't honestly recall the first that well, but the second had me seriously underwhelmed)
Akira (brilliant but so much less than the manga)
Serial experiments Lain (just couldn't maintain an interest , i'm told it's fantastic, but I was bored to the point of stopping by episode 4 or 5).
the famous films by Hayao Miyazaki (they were beautiful to be sure, but mostly just fantasy stories and any allegory was fairly shallow as best I could tell)
Can someone help me ? I really prefer the science fiction to fantasy, I should say I REALLY prefer science fiction to fantasy and the harder the science the better.
I can't imagine there haven't been more things like GITS:SAC produced since then.
That's my rant. Where the hell are the cool things that I'll like ???
