Sound - I liked it...
Now, normally I don't like watching OPs or EDs of anime. A lot of the time it spoils the mood with the unchanging song during the climax of the anime. As such, I usually skip past the OP and start the next episode before the ED. This was not the case with Tokyo Ghoul(sort of.) From the very first episode I found that I immensely enjoyed listening to the OP. With such a short anime (1-cour), the OP pretty much fit the mood for every episode. But even with such an amazing OP, I did not enjoy the ED at all. Even right now just after finishing the last episode I can hardly remember the beginning of the song simply because I barely listened to it. As for the background music, to me, it's a matter of did it stand out, or did it blend nicely? In Tokyo Ghoul, all I can really say is it blended in nicely. I mean, it's background music. I hear it, it fits the mood, and it changes.
Story - Good enough
After watching the opening of the first episode, I noticed Kaneki with white hair instead of black hair. Hair changing in anime usually means the character becomes a badass. As someone with absolutely no background knowledge, this was pretty much the one thing I was looking forward to in the beginning. Thrust into the ghoul world pretty quickly, Kaneki struggles with the morality of eating people. He is forced to live on the grey line that divides ghouls and humans. The beginning of Tokyo Ghoul allowed the story to go in many places. So, when the story slowly unraveled, it's safe to say I had higher hopes. Still, throughout most of the anime, I was kept on my toes, waiting for the appearance of white-haired Kaneki. Suffice it to say, I didn't want it to end at episode 12. The story was good enough that I'll probably be reading the manga in the near future.(something I rarely do.)
Character - ehh
While the character development was quite good, each side character got a little mini-arc of their own, and then proceeded to scarcely show up for the rest of the anime. When one such side character was brought back in the end for the climax, the only thing I could really think about was, this is really cheesy. While I do realize there was only 12 episodes to work with, the amount of screen time each character got felt a little short. Rize had one of the weirdest roles in the anime. Trying to incorporate her into the anime was quite awkward at times. The main problem with Tokyo Ghoul's characterization was simply because there were too many characters. Many characters could've had a completely different personality and it wouldn't have affected the story at all. They're pretty much there to fill up time and space. I'm not talking about person 924 in the crowd on the streets, I'm talking about much of the "police force." For example, one of the commanders just irrationally gives out orders and gets angry at pretty much everything. He doesn't even need to be there and things would still work out. Also, the whole police side of Tokyo Ghoul was really left untouched and had a lot of room to expand. Mado is really the only "policeman" who actually has any decent character. Still, the characterization wasn't bad and for the main characters, it was very good.
Enjoyment - interesting
As the anime was airing, I did in fact watch each episode the day it came out. It was that good. There are some memorable scenes that people poke fun at and the ending was a particularly powerful one, especially for an anime that's only 12 episodes. If I had to rate this, which I do, I would give this a 9/10. Don't ask me why, it's just an arbitrary number for MAL.
