Ah, pity, the Sourcerer is probably the single best hacking villain I've ever seen. Hammy beyond belief, utterly terrible actor and of course totally inaccurate.
I did not say that. The drawing is pretty good. Sure looks better than Clear Card too!
No, I don' think there'll be anything weird. Other than the film being a bit too like an anime film and not enough like Cardcaptor Sakura, but I've complained about that at length before. The villain of the movie is voiced by Rei from NGE, but I said that before.
Insomnia sucks. Luckily, while I have major issues actually falling asleep (sometimes takes hours even though I'm dead tired), actual phases where I can't sleep at all are fairly rare. I barely ever sleep enough and often go for weeks with only 2 or 3 hours of sleep a day, but it's always at least a bit. Hope that'll clear up for you soon(ish). Seems to be a general trend with our forumites too, judging by the other thread about daily experiences.
Talking about otakus is not that easy. I don't remember much about the quality of the documentary, to be honest, only that the people interviewed were stranger than I was at the time, which was pretty impressive. Nowadays I know that Japanese society as a whole is stuck in a place between insanely complex social norms, tradition and fast paced modern life, so counter-/subcultures have to be even more extreme (than ours), and kind of naturally end up being complete outliers in terms of human behaviour.
In general though, yes, football ultras are the dregs of society once they turn from being utterly devoted to harmful, which invariably seems to happen. As for being devoted to things that don't really matter, who am I to judge? Live and let live, as long as they're not harming anyone else it's all good, as far as I'm concerned.
