YES, I was quite shocked myself!! Actually, the episode has quite a Dystopian-Monogatari-esque feel to it, which is quite new to me so it colored my suprised!! I'd say, The artistic expression is one of the greatest point of the episode, it really managed to make the most out of it, It isn't quite clear to me where the story really wants to go but then again, it's just the first episode, its too soon to say anything about that, I'll give it a benefit of doubt and see whether it's actually good or not!!!
