Hmm, I finished this show recently. Apart from episode 1, which didn't make too much sense till I read the manga, and episode 7 which was boring, most of the episodes had me cracking up completely. I think my favourites were Pyuui in ep 3 and
However I hated^10 the weak, cop-out ending that this series had. It's like the whole series was aiming towards one point and at the last moment the writers just shied away in fear and settled for what would make the viewers happy. I was so pissed off when I watched that part, I haven't really been able to recommend the series to anyone else, but it makes good watching for anyone who likes crazy comedies.
EDIT: Even if you hate FLCL and Excel Saga like I do, you might still like Abenobashi, so don't let the fact that it's by the same makers deter you.
