How do you know an anime is encoded in 10-bit color?
It'll usually be written in the file name. The reasons why it's not done for everything is because A) it takes longer to encode the video (so don't expect a group like Horrible Subs to use it since they're speed-subbers), B) not everyone's hardware can handle it (slowly becoming less of a problem now), and C) not everyone's software supports it (again, it's becoming less of a problem).
Is that show a bit ecchi or you like it for other reasons? I was initially interested in that one when I first heard of it but then I hear the revenge aspect is dropped pretty quickly. That kinda reminded me a bit of a gender-flipped Watashi ga Motete Dōsunda (Kiss Him Not Me) where it was described as "a fat, lazy, pervy fujoshi in a hot body being pursued by hot young men who she actually ships with one another" which was fucking hilarious when they did it. But the show itself only gives you a tiny bit of that before it decides to become a regular romcom. If they had only played the selling aspect for all that it was worth, that show would've been AOTS. For me, anyway.
It's not ecchi. Makabe basically hates Adagaki because she treated him like shit when he was a little fat kid, so he transforms himself specifically so he can get with her and break her heart. Except she defies him all the way, with only occasionally showing cracks in her shell, which keeps him going. And it's funny to watch her continually shoot him down, which he completely deserves. But he gets enough progress to keep him on the revenge path, particularly since he gets help from an unexpected source (her maid, Koiwai). Towards the end they all start getting more buddy buddy, but it certainly never turns into anything romantic, which is probably why I find it so funny. I can just imagine the sappier people watching it getting tweaked every time nothing happens between the two mains.
My real problem with it is that it never ties things together with the past events, so the girl is always just a bitch when there's obviously some sort of convolution there that made her so bitchy. And then there's the other girl who was pursuing Makabe, Fujinomiya, with whom we see some sort of past connection but never an explanation as to what it is. I'm sure they were shooting for a second season, but, still, you have to have some sort of payoff.
I really, really want the live action movie to flop on its ass. I'm sure it'll still make money one way or another: either the domestic bo will be just enough or the Chinese bo will prop this one up like they did PacRim. Looking at footage, none of it looks impressive visually as far as scenery is concerned and the actors all look bored. It looks no different from something serialized on Syfy. The only thing I haven't completely written off is the soundtrack.
I honestly don't know what I think. On one hand, I'd like for it to succeed so as to get more money flowing in the anime sector...the rising tide raising all ships, basically. On the other hand, I don't expect it to be worth me bothering to go see it. I'm not a huge GitS fan to start with, it appears based primarily on Oshii's movie versions which I didn't like (wonder if there'll be a damned bassett hound somewhere in it?), and it doesn't look particularly impressive.
