The first season was decent although it was a bit rushed up but Root A was terrible!
Story - 3/10 After watching this anime, I might have to admit that I was really disappointed. I loved the manga but I hated the anime. Here are some reasons why I hate this anime :
1. Kaneki joined Aogiri Tree. Does that happen in the manga? No. He refused to join them.
2. They had left out most of the important parts. For example, about what happens to Rize and WHY Kaneki was turned into a half ghoul. They had explained everything in
the manga but all those things were left out in the anime.
3. Hide's death - I know that Hide's death is supposed to be depressing but it wasn't. And Kaneki kept on walking and walking in the last episode. I almost doubted that he'd ever stop.
4. There's a possibility that there will be a season 3 judging by how the second season ended. If they were to continue the story instead of making a reboot, then the outcome would be something worse than Root A.
If they had followed the manga, then I am sure that this anime would never get this much of hate.
Art - 4/10 Terrible! There's nothing much I can say about it.
Sound - 3/10 I listened to the opening once and I decided that I am not going to listen to it ever again. I always skip it. It's nothing compared to "Unravel". I have given 3 points for sound and that's only because of "Glassy Sky".
Character - 3/10 This season made me hate some of the characters, especially Kaneki. Joining Aogiri tree was the dumbest thing he did. The Kaneki in the manga is way different from the Kaneki in the anime. The same goes for the other characters. Compare that fight scene between Kaneki and Ayato in the anime and manga and see the difference.
Touka kept on running and running and running and running for so many episodes. Don't get me wrong. Touka is my favorite character in Tokyo Ghoul. It's just that running for four episodes looks ridiculous and it's completely unnecessary.
Enjoyment - 2/10 I did not enjoy it at all.
Overall - 3/10 It was a huge disappointment. I was expecting something better. They completely ruined something that should have been a masterpiece if they had followed the original story line. The only thing that this anime needs is a reboot.
