Some really really good anime from the top of my head:
-Shokugeki no souma
-Darker than black
-re:zero
-No game no life
-Code geass
-elfen lied
-parasyte
-haikyuu
-saiki kusuo
-claymore
-d.gray man
-monogatari series
-a certain magical index
-fate series
-btooom!
I've always found D-Frag to be a interesting anime if you like the high school setting, otherwise No Game, No Life and Sword Art Online are some of my other favorites.
