I agree with Zifei, Shingeki no Kyojin is amazing, and the plot twist that shall come to the anime soon.. Will be great
I'm a sucker for action/adventure/fantasy, I have seen many hundreds of anime shows, some are definitely better than others.. Off the top of my head a few I recommend...Hunter x Hunter 2011
-Loved the original, 2011 gets through the original a bit faster, then continues passed it, can't wait for next episode every week...Suisei No Gargantia
-awesome new show! minor mecha theme but Love it so far.Sword Art Online
-Similar to .hack//sign.. I thoroughly enjoyed it!D.Gray-Man
-Action.. Adventure.. Demons.. Hell yeah? One Piece
-Another Action/Adventure/Fantasy, love how they explore tons of interesting placesToriko
-Same as above, but makes me a bit hungry every time I watch a new episode...Btooom!
-Had pretty interesting horror theme to it. Was an interesting show to watch, though I probably won't watch it again.
