The visuals here are even better than the first season, and the character development keeps getting better. There are clear differences in character dynamics from the first season.. you can literally feel the growth. Sebastian and Ciel are genuinely closer and surprisingly care about each other. The action is also so much better; I would actually be interested and on the edge of my seat for various portions of it.
Above all, the music!!! I also love Black Butler soundtracks but this season was even better than the first in terms of sound. Even the comic relief moments had appropriate soundtracks.
I'm not necessarily super interested in the Grim Reaper scenes which is where I dock points. Thankfully they're not super involved in the plot, but whenever they did show up, I felt myself zoning out and feeling bored. They are the weakest link in this entire franchise. Maybe they're better in the manga but there's something really lacking in their interactions. What purpose do they even have in this plot? Literally nothing.
Overall, I always highly recommend Black Butler to anyone starting anime for the first time. It's such a classic and for any fan of supernatural or drama or action or even BL.
