Personally, I liked it a lot (just watched it now).
Carried a lot more depth to it than babysitter had (given the longer length, I'd hope so).
I think what a lot of people are nitpicking about is that this anime was based on traditional Japanese. IMO, I think this was a good fit for giving the elites a backstory, a lot of their nature and culture is based on some strong Japanese themes. In regards to the female elite, I can understand that she didn't appear in the game but for the anime, her role made sense. In the traditional Japanese view, women are seen as physically unequal or "weak" but that is because their traditional "role" is to support the male, which in Japanese culture would mean the woman must be just as strong as the man, if not stronger. I think I heard from another anime the expression "a sheath to encase the sword".. something along those lines. In that regard, everything made sense and I appreciated it because of it.
NOW, aside from that, some things were just too overtly Japanese. For example, their clothes? wtf?! Post-battle, the arbiter had a Japanese robe on (can't remember the actual name) and it just looked weird knowing they have "chicken" legs. They should've put more thought into the styling of their out of battle clothing.. yuck. Also, I personally hated the fact that the "samurai elite" was dressed in samurai armour. There wasn't even an attempt to mask the Japanese influence there, they just drew samurai armour, made him hunch over and stuck bent legs and an elite face on him.. mega-wtf?
Also, the animation was really smooth. I liked that it flowed, and not just for minor sequences like walking slowly or talking, but jumping and running were attempted to be as smooth as possible which was really cool. But why was it so grainy/ugly? It felt like I needed glasses the whole time, hope they clean that up a bit or something when they actually release it.
All in all, it was pretty good. You really feel for the arbiter and it was nice to see that not all the elites were mindlessly brain-washed to join the covenant like the game portrays (H1-H2).
Lastly, the 500ft hunter was super sexy. Super sexy in a shadow-of-the-colossus-aka-the-arbiter-man-handled-him kind of way.
