Agreed that the only thing it's lacking is better animation.
I love how this anime has subtlety and is not afraid of having the characters show their emotions when needed.
The way Jinya smiled was completely different from the way he did in all the previous episodes and he smiled more. Very different from the Jinya who had such a heavy conscience a few episodes ago.
The way things are being written I'm expecting imouto to go through her own development at this point.
