The obvious: 90's era, similar feeling of the art -> somewhat depressing story that progressively Gets Worse as it goes on -> Bad Futures/humanity is half gone -> there clearly are no therapists left for these messed up characters.
+mecha? Well, NT, HT has robots but I don't know if they'd count as mecha ->
+epic mood whiplash from the in-series nightmare fuel in the form of "Fly Me To the Moon" and "Lullaby..."
