Sorry if I get sidetracked, that's just how my brain works and I'll try not to be.

I really enjoyed this series. I liked the anime as well, that's actually what got me into the whole thing. I won't compare it to the anime, because I think the manga is on a different level.

Story
7/10
I thought the story was intriguing when I first heard about it. I love dark stories, so naturally this was an enjoyable read. The idea of ghouls eating people was creepy and I loved it. It starts off a little slow, but as I get absorbed into the story more and more, I find myself loving characters I didn't like that much at first (more on that later). Back to the story. I don't know what else to say except I remember this story brought me to tears a few times, especially Kaneki's inner struggle.

Art
8/10
Disclaimer, I am not an artist, but I can draw a pretty mean stick figure. Jokes aside, I liked the art a whole lot in TG, it really added to the dark atmosphere and who doesn't like that?

Character
7/10
I loved a good amount of the characters, I feel like some of them could have been more developed a little better, but maybe that's not a bad thing. It's more realistic to me when some characters are not as developed, since in real life I don't spend a hell of a lot time getting everyone's "backstory". Can't speak for you, though.
Anyhow, I LOVED Kaneki's character development throughout the series, you can just feel the raw emotion, the anger, that he has about being a ghoul and being abandoned. I could go on forever, but I'll attempt at keeping it short. I feel like I could relate to Kaneki, not on the ghoul level (or could I?), but from a perspective of mental illness, the whole "why me?" self-pity and denial that comes with it. Sorry if you can't relate, but that's just what hits home for me. I feel like the whole part with Jason just took my heart out of my chest and threw it in a blender, then stomped on it right after. I cried, I'm not afraid to admit it.
The other character I wanted to discuss based on his character was Juuzou...oh my god. For lack of a better word, I was very "meh" about him at first, until I read his backstory. I love how dark and twisted it is, I feel so bad for him at the same time. I am fascinated by his psychology, and it breaks my heart at the same time.
Lastly for this long-ass thing, my favorite character from TG is...*drumroll* if you couldn't guess from my profile, Tsukiyama. He's just one of those characters, I guess.

Enjoyment
8/10
I'd be lying if I said I didn't like "mainstream" anime, I find it interesting and I don't really care if "everyone" likes it. But anyway, I thoroughly enjoyed Tokyo Ghoul. I loved it from the start (haven't quite finished it yet, but I'm catching up).

Overall
8/10
Tokyo Ghoul gets a high rating from me, as you could have probably guessed. I enjoyed it, and I'd recommend it to anyone who likes creepy/horror manga.
