I was thinking, letting my brain randomly wander through the maze of my imagination (which is pretty much always a bad thing), and it wandered toward anime. I started thinking about my two favorites (which are Durarara!! and Tiger&Bunny) and why I liked them and if I could only choose one which one would I choose.
Turns out I couldn't choose and I started to wonder why.
Leaving technicalities aside (everyone knows I generally have a thing for good voice acting and both of those anime made me start to fangirl over a lot of "new" voice actors) I quickly realized I liked them both equally because they each appeal to different things I like.
Durarara!! is a fest for my brain. Tiger&Bunny made me cry so many times I stopped counting.
Unfortunately things aren't that easy because if you think about it, I wouldn't have liked Durarara!! as much if I wasn't that invested in the characters and didn't want them to be happy, and it's not like it didn't emotionally affect me either. I can say the same for Tiger&Bunny, sure it made me cry but it's not all there is to it, I/we have easily spent countless hours talking about damn theories about this. We still do.
So now what? Is it all about a good balance? It should be about a good balance but on the other hand it isn't really.
Why? Because we each have different emotions and each react to different things. We don't always like to think while watching anime because after all it's entertainment.
If I take Tiger&Bunny as an example, I liked it that much and it is and will stay one of my favorite anime of all time because I could relate to the characters and their story to a point I didn't know was possible (too much if you want my opinion), it's pretty much the reason why I could get into it so much.
The characters in Durarara!!, well, it was much harder to relate but the story is what drew me in.
That being said, I can't possibly answer the question I titled my post with, because to be honest with you, most of the time, it's my brain who's enjoying anime the most, because, most of the time, the things that are supposed to get me emotionnal don't, for various reasons.
Not to mention it usually feels so artificial that it pisses me off more than anything else.
So I guess that for me enjoyment of the brain comes first, I'd much rather just have fun than being touched if it feels forced.
Probably why I don't usually like romance anime.
