That Depends are あなた looking for a certain Genre and are looking for an アニメ to be in a specific language? (like English,the original Japanese etc.)some アニメ that come to mind are..Fairy Tail (which is a very funny anime!,and it comes in dubbed also),Kuroshitsuji/(also known as Black Butler in the dub) is a very good アニメ too!,Fullmetal Alchemist is a good one too...it can be a really sad アニメ too..Azumanga Daioh is an extremely funny アニメ same can be 発言しました for Lucky 星, つ星 (though it's a bit もっと見る random),Fruits Basket is a cute アニメ to watch also,then there's also The Melancholy of Haruhi Suzumiya! that's amazing too! Ouran Highschool Host Club is also a great anime! it's really great!..One Piece,Katekyo Hitman Reborn(It's Only in Japanese though) and finally InuYasha..and those are the only アニメ I can think of now,anyway hope I helped!
