I couldn't believe how disappointing the whole experience of revisiting old mysteries turned out to be:
Five episodes later, and the show had done nothing more than compound more mysteries upon what was already a rather puzzling story. It was then, a week or so ago, that I realized that it wasn't the mysteries behind a series that enthralled us about Otaku, or at the very least, it was only part of the puzzle.
It was the revelations that held the secrets to a perfect mystery, when everything that we wished, hoped for and expected is either brought to life in the most spectacular manner, or blown out of the water with an earth-shattering twist. The less of a revelation we see coming, the better. And here is where Chaos Head failed. None of the mysteries it spends entire episodes building ever amount to anything - at least not in the time that I assigned the title.
In the end, I spent 20 minutes prevailing through a sixth episode that seemed to painstakingly stretch over an hour. Here the hero learns some truth behind the peculiar experiences surrounding him, and he believes it, at which point it brings him some much-deserved peace. But I couldn't, believe it that is, because it didn't make any sense, none of it; and the fact that the protagonist could swallow some random inconsistent explanation from a total stranger seemed rather absurd.
After going 'huh!' for the umpteenth time during the 'big reveal', the credits rolled, I exited SPlayer and deleted the damned thing from my desktop, utterly infuriated at the time I had poured into those six episodes.
I would recommend anyone into mystery thrillers to check the Chaos Head series out, but I doubt anyone will have the patience to sit through all 12 episodes. On the plus side, I realized that despite my brain's inability to recall the reasons why, every anime in my 'will never watch' pile made its way in for a reason.
