I really like the fast pacing, it strengthens the non-stop action a lot and I think it's what this series is aiming for. Sakamoto and Himiko's relationship is so very lovely, it was kinda hilarious how they had that moment of embarassment seconds after the horror they went through.
Also for some reason Taira-san is less sympathetic than he was in the manga, or maybe it's just me but I just didn't feel much when he begged Sakamoto to stay.
Oh and I guess it's now safe to say that Tyrannos Japan is probably running this whole thing to score on stuck-up rich assholes with too much influence and/or immunity.
edit:
I find that Himiko's voice actor (Suzuko Mimori?) has been doing a
great job thus far. Her voice has a kind of charm that doesn't really stand out but is really likable to me.
