Hm, for some reason I wasn't that impressed by this episode. I mean I have read that arc in the manga already. but I still thought I would be more shocked by what I am seeing on screen.
I liked the scene with the demons, that was well made and was also able to utilize the CG backgrounds to its fullest potential, but otherwise everything was really bland.
The colours were not popping, the backgrounds are awful and the animation was nothing special either. Nor was the direction inspired apart from a few highlights here and there.
This is supposed to look like a fantasy within reality, but the colours and the tone make it seem so dull. OP was too shounen-ish too.
ED was amazing though.
