FFFFFFFFFFFFFFFFFFFFFFFFF I fucking hated this episode. Lucky I actually stomached it enough to continue on to episode 5; at the time I'd thought the entire rest of the series had been drawn this way.
God curse that fucktard who co-directed that episode.
You know, while I much prefer the usual style, I really don't see why episode 4 evolved into a massive shitstorm. I mean, it was, for all intents and purposes, it was a comedy/filler episode (or as close as TTGL got, save the recap episode) and got a comedy art style.
Of course, the comments from the director highlighted above are a separate matter.

Well, Osamu Kobayashi did do this episode.
Anyway, I've always liked his work and this was an interesting episode since it was essentially his usual style of direction, but then more zany and geared towards the spirit of the show.
ALSO, as for quality complaints, to be fair, people should see Hiroyuki Imaishi's episodes for Abenobashi...
If you talk about radical differences in animation direction, his episodes' art pretty much had something really rough compared to the rest of the show...
(but then, the show also did dive into like several different styles, so, in that context, the difference made sense)
This style really wasn't suitable for this series. The whole thing about the characters having crudely-animated square mouths and visible jowls that make them look like they're in their 40s-- and generally looking off-- only fit those pink creatures they fight later in the episode. Even then, they end up looking like the stick figure characters in images made for 4chan (minus the body).
Ep 4 was designed by the guy that animated Beck. Strangely, that one is an amazing series, but unfortunately the first few episodes looked a lot like this one.
