Integrity of animu huh? It's all in good fun, what's wrong with a lil moeblob every now and again. Anyway, boy was the original broadcast of Haruhi a lot of fun, well it was anyway til Haruhi mania took over and everyone was loathe to associate with it.
See exhibit A:
Best thing ever, or worst? You be the judge
I personally don't think that moe is something like the first horseman of the anime apocalypse.
A lot of new shows are overdoing it, but it's pretty easy to avoid these infected shows.
I don't know much about how anime changed over the years, but I can't imagine that there was soooo much less moe involved in anime 15-20 years ago.
Maybe the cancer already grew too big in me, but I can't imagine a world without moe anime :P
I'm also not sure if the world would be a better place without them. It can't possibly be that all the moe anime studios suddenly start producing incredible and innovative anime once the moe phase is over.
Was there really that much hype around Haruhi?
All I know is that I'm really enjoying it so far :)
