The Tank Police are insufferable human garbage and Leona is worst for her contradictory "it's the human thing to do!" spiel, yet the absurdist self awareness (or complete lack thereof) is the formula for entertainment. It asks you to stop thinking, sit back, and enjoy while the characters revel in their vices.
I have to commend the latter half of the OVA in particular, which focus on the recurring "villain" Buaku. His obsession with the past and eventual coming to terms with his own existence seems to have had a great influence on how Shirow approached the philosophies of artificial life in Ghost in the Shell. Dominion is worth watching for that alone. That, and pre-2000's feral catgirl designs.
