I'm not gunna list good animes that are out there, like others... instead I'll give ya a bit of advice:
I'm not losing interest in anime, but not as interested as I used to be. If I find a REALLY good series it';s different though! But... a lot of the new stuff doesn't look too appealing...
My advice? Ok, some new stuff doesn't look as good, but it's surprising how much good stuff you'll bypass! I noticed this "AIR" anime on Animenfo a while back thinkign "ok, whatever" heard some good things and looked into it, and it's such a great series! Think you just have to find the right series or in my other case, look back for some slightly older stuff that's good. Took me a couple years (AFTER popularity) to watch things like Wolf's Rain and Witch Hunter Robin etc.... actually ALOT of great anime came out in 2002... it was a REALLY good year!
So yeah... but even then, anime IS a phase, but no one knows when it'll go away for them^^ But hey if anime isn't your thing anymore, you can always try manga
