GITS and Patalabor are the exact same thing. Its a mecha show about future technology and then they unload a bunch of shit on you constantly with little to no backstory or explanation or whatever the fuck is going on and just assume you'll make sense of it later.
Its really poor storytelling, but they get away with because everyone leaps to fill in the gaps because they found the characters amiable and the story somehow comprehensible, even when it is deliberately presented as incoherent drivel.
It's shit, but compared to 90% or the other mecha/sci-fi anime its pretty fantastic because of the character designs, BUDGET, and fights.
Please don't take it too seriously.
