At first this manga might not have the most original concept or story. However, the way in which it is executed is excellent. There are no such things as 'black and white' in this manga. Each important character has proper development and significance to the story, and none of them are there just for the sake of them being there, nor are they useless. The characters have realistic personalities, and none of them are just 'good' or 'bad'. Each character is well developed and continue to develop and none of them are completely innocent just like how it is in real life. I appreciated the factthat the characters are like this and this manga understands this perfectly. Characters that may seem shallow at first actually have depth to them.

Ken Kaneki is by far one of the best developed characters I have had the pleasure of seeing. He is not just the 'nerd' or the 'cool emo badass'. Just like any person in real life, he does have secrets he wants to keep buried and not willing to accept. He has various stages of development that actually makes sense in the situations he is in. His motives and thought process is excellently displayed.

Another good thing is how the manga does not just spoonfeed you the facts. They are foreshadowed with various references to numbers, tarot cards, symbolism and metaphors, but unless you pay attention to what you read you will not notice them and not be able to appreciate the manga in its full glory. I would recommend not just reading the manga just once but at least several times to get what you may have missed.

Overall an amazing manga, and the cliffhanger ending was actually the best way to end the first part.
