Story- 8/10 - The story is well written and they do a great job taking from the manga, obviously things are gonna get left out or the time of an event may change but nothing to truly ruin or change the original story line. It stays enjoyable through its entirety, Throughout the series it has some very graphic parts that give it the horror feel but it's still a very enjoyable watch even for people not super into gore.
Art - 9/10 - The art is fantastic, not just the character's but the scenery as well. The different ghoul's kagune look awesome in color and motion ( especially Tohka's).
Sound - 10/10 - The music for this is just amazing i really cant praise it enough. The intro is the perfect song for this series, TK from Ling Tosite Sigure has a very unique sound to him and it just fits so well with this dark and unique story.
Character- 8/10 - The characters in this all have very unique personality's that you get to experience,They all become rather lovable , even the bad guys, While Kaneki may be the main character you really get a feel for a lot of the cast, who they are, what they like to do, their past, it feels like you're watching over a city as it's story about ghouls and investigators unfolds and not just watching 1 character go through life and the struggles that come with it.
Enjoyment - 9/10 - I personally really enjoyed this, enough to watch it several times over. The story is intriguing and there isn't a lot of filler like some anime's have. With only 12 episodes to work with in this season they did a great job keeping it interesting and moving the story along at a decent pace.
Overall this is a really great anime, i recommended reading the manga first then moving onto this and the next season so you can really get the full experience of what the author has to tell. I did my best to not do any spoilers ( which is tough cause i totally want to rant about this explaining why i rate this so high among everything i've seen, but no spoilers for you!)
