I enjoyed this show a lot more than I thought I would! Oddly enough it reminded me a lot of Bungou stray dogs, which was a show that I didn't really enjoy. But this show, in my opinion, was better. It had a different aura around it. It was more serious but still had the occasional joke moments.
I also liked the relationship with Ciel and Sebastian. I didn't know if I would when I first started watching it but I really grew to like them. One thing I will say that I disliked about the show was the amount of filler it had.. which was a good amount! It's okay (I watched Naruto in it's entirety so I'm used to filler) and it didn't throw off the show that much but I was kinda hoping it would have less of that.
Overall I gave this show a 7/10.
