My default approach before seeing 1st episode was "this is re-boot, so this MUST be MEH"
After watching this I think it's not THAT bad.
Different art style, not exactly my taste, but still well done: dark, gloomy and futuristic.
Nice animations. Not hand-drawn, but you can see that lot of attentions to details was involved, so it's not "render f*.* everything with same settings and dump it into movie" approach. I kinda like it.
Music at least as good as in GitS or SAC.
Plot seems to be a bit chaotic and fragmented in my opinion, but hey - this is just first episode, and to be honest plot in previous movies were not very clear at the beginning either.
Bottom line is, while I was not amazed (like with GitS), I also do not feel that time spend watching this was time wasted. If they do not screw up the remainig episodes, it will be a solid product.
