I used to be really big into anime, enough to fill up 3 hard drives full of it and take Japanese for a year. I was introduced to anime my freshman year of college by some guys in my dorm. They were into the typical action series, like Naruto and Trigun. I liked the shows because they were fairly entertaining, and, at least for the shows that we're still being fansubbed, a lot more easily obtained, which was a major plus because I didn't have any money.
I didn't really get into anime until one of my friends casually mentioned that a particular show called AIR was worth watching. I copied the series from him, watched it, and I was hooked. The series was a sort of supernatural drama/love story with a very... emotional ending. I cried for hours after the ending. After then, I voraciously consumed every dramatic series I could find.
I'm not very emotional, and at that time, I thought I might be unable to really feel much emotion at all. My external world was, and still is to a degree, rather devoid of emotion, or at least any emotions I liked (I mainly just get stressed and embarrassed). Somehow, these anime series presented an accessible world to me. I could often relate to the characters, who seemed to be much more likely to be introverted than in mainstream American media. I could be emotionally involved. Whether they were light-hearted comedies or heart-wrenching tragedies, I was pretty much addicted to the emotions I got from them.
I don't know how to fit it in with being an INTP very well though. Maybe it's a case of having a severely underdeveloped Fe.
I don't really keep up with the whole scene anymore though. I watch an occasional series now and again, but it seems like it's gotten harder to get my fix from anime. I guess its because the originality and novelty has worn off. Plus, it's gotten harder to get episodes, since my university has clamped down on P2P and Bittorrent hard.
