I just finished getting caught up on the show last night and I have to say I love this show. Has so much potential, I just hope Fox doesn't pull a Firefly here and cancel it because this show is awesome.
Have to say I was rather surprised by how low tech some of the weapons are. You'd think with synthetics around they'd be sporting much more powerful weapons then just your average, everyday guns. The tech they use though is pretty amazing. Like the spray mask that screws with cameras, was a rather nice touch. The one thing that sells me on this show though is the interactions between Dorian and John. On one hand you have a synthetic that was made to act and emulate like a human that is also trying to learn what it is to be human and you have a damaged cop who's basically relearning who he is (the first episode basically answers why he's relearning). Just my take on the premise of the show. Their banter is priceless (Dorian cracks me up, especially with the whole online dating profile thing. Damn near lost it when he did that).
Out of all the synthetics the only ones that appear and act human are Dorian (DRN) and those sexbots from episode 2. The MX series AI is just to robotic to emulate a human, then again they were made to be just like that (no emotion, just logic based programming (acting a lot like Spock)). AI like Dorian's is far off but honestly it'd be amazing and creepy at the same time to meet something so human but know it's actually a synthetic emulating human behavior. If that happens we might just be living in a GitS universe (which would be totally awesome).
