So I tried searching for a Tokyo Ghoul thread but I couldn't find one, so I decided to make one.
Tokyo Ghoul is a relatively new anime, only 12 episodes so far of which the last for Season 1 was released yesterday 18/09/2014, it seems there will be a Season 2 starting January 2015 but Season 1 in itself is animated really well and is a great watch so I recommend watching it for those who have not yet seen it!
Here's a synopsis that I have taken from MAL for the anime:
The suspense horror/dark fantasy story is set in Tokyo, which is haunted by mysterious "ghouls" who are devouring humans. People are gripped by the fear of these ghouls whose identities are masked in mystery. An ordinary college student named Kaneki encounters Rize, a girl who is an avid reader like him, at the café he frequents. Little does he realize that his fate will change overnight.
Here is a video of the opening in HD.
