I recently went on a binge and found really good ones!
Log Horizon - good plot, though familiar. Similar to Sword Art Online, but sufficiently different.
Tokyo Ghouk - my first trek into horror anime territory. So Good! Brutal though.
Deadman Wonderland - also brutal, but intriguing. Mysterious and some laughs.
Zankyou no Terror - one season anime, SOOOOOO GOOOOOD! Highly recommended! Seriously, this was anime gold! Watch.
Beyond the Boundary - really good start and middle, though I fee the ending was rushed. Still highly entertaining!
Everyone knows Attack on Titan, of course.
