In case you watched everything that was mentioned above, I picked some little less known but still good anime.
As always, tastes differ, but most of these generally have positive ratings at least. In no particular order.
Koi to Senkyo to Chocolate (School, Drama, Romance)
Amagami SS (100% Romance for those interested, explores multiple routes)
Magic Kaito 1412 (A gentleman who steals jewels with magic, episodic)
Death Parade (Hmmm... just look it up, highly recommended)
Hyouka (Slice of life, Mystery, Highly recommended)
Little Witch Academia (Mahou-Shoujo Movie, has a good ending)
UN-GO (Mystery, supernatural aspects)
Working!! (Workplace comedy in a family restaurant. Highly recommended)
Overlord (Still airing, pretty good twist on the trapped in game style, not bad though, turns into fantasy)
Trigun (older Sci-Fi with action and light comedy)
Mushishi (Seinen, slow pace, but each episode is like "Man, that's deep")
Teekyuu (A special kind of comedy. High school girls on crack who play tennis)
Phantom: Requiem for the Phantom (Dramatic action thriller, some violence, few cliches, highly recommended)
Redline (qt romance movie, sci-fi romance revolving around racing)
Sayonara Zetsubou Sensei (Dark comedy, shoddy animation, but good overall-ish. Niche audience)
Danshi Koukousei no Nichijou (Very funny comedy for guys)
Persona 3 The Movie(Based on Persona 3 game, dark, but very good action, drama, supernatural. Series of 4 movies, 2/4 released so far)
