It's hard to choose a top list. DBZ, Yu-Gi-Oh, Gundam and Card Captor Sakura are my nostalgia favorites.
Movies I love Akira, Ghost in the Shell, Paprika, and everything Ghibli.
Modern stuff there is so much I can't choose, from Lucky Star to Gurren Lagann to Kami Nomi to Kill La Kill.
This current season I've been watching Kiznaiver, Netoge, Hero Academia, and One Piece.
