Watched the first 4 episodes last night and it was really cool. The camera work is really good, it gives the giants a real feeling of scale and immensity. The flying debris when they go crashing into the ground is a nice touch too. They seem heavy and large and a lot of it is because of the angles the cameras are framing them in.
The story and characters so far are interesting and it was hard to stop watching after 1 or 2 episodes. I'll probably watch the rest of them today since there's only 7 or 8 episodes so far.
At first I wasn't crazy about the big blue eyes on Geed but after the first couple episodes I got used to it and there's a reason why they're like that which made sense.
