One downside of this anime is that it does nothing to explain how exactly ghouls came about to be which is a question I and many other have. Along with this most of the anime is spent following the story of Kaneki Ken. And while it makes sense since he is the main character the anime had many other interesting characters that I would have liked to see explored more.
The fights are awesome to watch and the animation is top notch so there are no worries about jerking movements that disrupt enjoyment. Another good point about the anime is the music. Unravel by TK is a song that helped make this anime as popular as it is and it went viral for a reason. The song is amazing and once you read the lyrics very thought provoking.
This is an anime that I recommend to a lot of my friends and its something that I would say you should watch too.
