I felt that Kyojin was pretty good so far, not 100% thrilled with the OP song but the anime itself seems to be doing fine, albeit progressing very slowly and at times boringly.
Tried Mushibugyou and, unsurprisingly, the "blatant fanservice" made me delete it immediately.
Definitely slow but not boring. I think the slow start is even necessary. Pacing seems good. OP is done by Revo (Sound Horizon). Not bad. :)
