Code Geass, Katanagatari, NHK ni Youkoso, TTGL, Death Note, Sword of the Stranger, The Sky Crawlers, Kara no Kyoukai, Kaiba, Darker than Black, Seirei no Moribito, Mononoke, Mononoke Hime, Angel Beats (end sucks), Clannad (may be zzz), Fate/Zero, Full Metal Panic!,
Most of them are at least 8/10 in my scale which is very strict, some have lower score, but should be watched IMO. I know some more epic series, just don't remember. I haven't watched many, too.
As for the current season, nothing interesting rly. SnK is mhkay and the rest doesn't meet my "requirements", but I'm picky. The upcoming season (well, it has just started) is going to be a lil better, though nothing special.
