It's weird with all the controversy revolving around episode five of Shinsekai Yori and how a lot of the complaints seem to be how 'bad' it looks (from what I've noticed at least) but I honestly thought the episode looked fine as far as the art goes. The backgrounds were detailed and the interesting color pallete kind of accentuated that dream-like atmosphere they were going for. Probably the only discrepancies, besides the stilted animations, were the noticeably different character models for this episode. They don't look bad at all in my opinion but it's still weird given that the look of the show has been consistent for every other episode.
The actual direction and the (mostly) incoherent narrative is another story though...
