Honestly, I'm disappointed.
The new character design is just... wrong. I appreciated how Motoko in all her previous incarnations was an able looking adult that matched her job and personality, but it looks like that's been tossed out the window. The final shot at the end of the opening sequence (with Section 9 standing together) is particularly cringeworthy. Okay, I get that this is a prequel - that doesn't mean that she should have the body of an emaciated child. I had some serious misgivings when I saw the initial character art weeks ago, but this is really worse than I had anticipiated.
The design of the (medical?) robot in the trailer looks silly to me.
The faces of the other members of Section 9 seems off -- it seems that the lead artist has trouble with eyebrows, and tends to squish character's facial features together to the center of the face.
The music is promising in some ways, but overall just isn't working. The theme in the titles sequence is atmospheric but lacks emotional strength - it's pleasant but hollow and too "light". The voice samples are a big part of the problem here. The "action" music in the second half of the trailer, on the other hand, is all sorts of bad. Generic guitar, oh, I'm enthralled. It;s poorly composed, nor does it feel like gits.
