I strongly recommend you to watch "Shingeki No Kyojin", now final episodes are released. You can watch directly the movies which are covering the season 1-2. But from Start of season 3, watch episode by episode. Besides as a master of piece, please try "Death Note". Did you watch it? I can write much much more:) What is your fav genres?
