Honestly, personally to me, besides the censorship of blood in the first few episodes, this is, overall, an alright season. I watched the last seasons and they were pretty alright with animation style, story, characters and even music, then this comes along.
And, in this season, I felt the characters acted alright and natural to their environment and how they usually act, the story went well with some tear jerking backstories and interesting twists, and although it could be abit overwhelming at times from the twists, and, again, as much as art was off or censorship was there, censorship happened a few times in the beginning of the series and the art generally holds up to a mid-tier level, which still lead the series to be enjoyable for me. I think this season at least deserves a 5 or 6 (including taking off a point for the censorship), for how I think the story, characters, art and the general entertainment of this season is. I don't know how exactly anyone could skip all that and write it off mainly for art quality or censorship.
Either way, I think there's a nice season here. Yes, it can use abit of art improvement, but I think everything else still holds well on it's own and the art is okay enough quality for me.
