I, needing a single particular screencap, slowpoked my way to the initial few episodes of Gurren Lagann from the first DVD. I got what I wanted halfway through the first, but stuck around a bit.
It put me off, but not for no reason. Now, I admit that while I didn't participate in any trolling or arguments about it, /a/ certainly biased me against it somewhat, though I had one from its outset due to an anti-mecha sentiment stemming from being assaulted by various toy commercial anime and TV series from a young age. And being a physicist. But the thing was this...the spiral motif. Knowing exactly how the story would progress and ultimately end for the mere fact of having been on /a/ since before the series started didn't latch me onto any suspense very strongly. Copypasta ruined any interesting elements of the writing since obfuscated plot summaries disguised as analyses were just used as page-filling trolling.
But the spirals really drove me away. I used to hang out with the bad crowd on the internet -- conspiracy theorists, mathematicians, Tool fans. I'd had enough of every single thing, mathematically relevant or not, being pigeonholed into a paranoia-inducing worldview involving fractals or spirals before I even read Uzumaki during the horror manga fad in /b/ a few years ago. Then blah blah, robots with faces and some yelling. I believe it was technically accomplished and to some degree artistically relevant. I had no need to watch the whole thing, as it'd only annoy me. I wonder how incoherent trying to write long things like this in this four-line comment box makes me sound (usually when I reread after posting: very).
Also, I am the person who, without any Japanese knowledge, edited the h-manga now colloquially known as "Food Network Hentai".
