So yeah, Japanator made a
top 50 animes of the decade. Many titles from the list are some of my favorites, like
Black Lagoon,
Gurren Lagann and
Death Note. Many others I don't know
yet. And many others I don't like, but hey, that's called
having an opinion. Everybody have one. Everybody have their personal favorites. And to my surprise, there is a bunch of great animes I really consider masterpieces that didn't make into Japanator's top 50 animes of the decade.
This is a top 10 of honorable mentions.
MY top 10. To me, all of them would fit perfectly fine in a top 50 animes of the decade. These are not my top 10 favorites of all time, nor the top 10 of the decade, I did not include animes that are in Japanator's list. You are free to disagree, but who knows, maybe there's some good titles out there for you to know, watch and have fun!
So, let's get 'em rolling!
Basilisk is the anime adaptation of the famous "The Kouga Ninja Scroll" novel, by Futaro Yamada, published in 1958. It's a love story, it's action packed, it's beautifully animated. Two ninja clans are in war, and 10 of the best ninjas of each clan fight it out to decide which is the best. Of course, the love couple is divided between the clans. It's like Romeo and Juliet, but with ninjas. Sinister ninjas with bizarre powers, exagerated, but far from being a Naruto rip-off. Basilisk is way better. Believe it!
Yakushiji Ryoko is probably the most elegant female anime character ever. She is the chief of a police department responsible for investigate supernatural cases. Her name isn't in the title of the show for nothing, she is the center of the story and what really make the anime shine. Think of Yakushiji Ryoko as a grown-up Suzumiya Haruhi, but with power to acomplish what she wants. A note-worth scene happens at the end of the 13 episode series, when Ryoko hides in a closed mall while soldiers and tanks are after her. She calmly takes a bath, change her clothes and face a tank wearing high heels and a red dress. Yes, she is badass like that.
Tenjou Tenge is one of those animes that ends with much story to be told yet, when the manga proceeds on it. But I consider the anime superior anyway. The theme is one of my favorites: martial arts in high school. Yes, the anime features big boobed female characters, but it's far from being a Ikkitousen, at least the anime is, where the pervness is scaled down a bit. The action scenes are great, just watch the first 5 minutes of the second episode and you will know what I mean.
Casshern Sins is actually a new version of Casshern, an anime made by the Tatsunoko Studios in... well, when the dinossaurs still lived on Earth. Sins is not a remake, it's a new version in its entirety. The world is occupied by robots. Casshern, with no memories about his past, is the responsible for killing the goddess of the world, thus spreading the destruction of all, and obviously, he is the most hated being in the world. This anime is extremely meaningful, the best anime yet to question life and death, and this is kinda weird, since it features robots. But it really makes you think.

At first,
Chrono Crusade may look like it is a light-hearted story about a girl shooting monsters in the face, but it has a deep story about a demon seeking redemption, and a girl who is up to anything, even giving her soul, in order to find her sick brother. It can get somehow annoying when you discover that the main villain is responsible for every characters misery, but it's a beautiful story yet.

Another one by Tatsunoko Studios, this is a series of short OVAs.
Karas are powerful beings responsible for protecting each city. Youkai lives in the cities, but most of the time are invisible to human eyes. The OVAs tell the story of a former Karas, who plans to take over the city. In the very beginning of the series, a fierce fight between the main villain and the actual Karas show a great mix of standard animation and CG. The visuals are great, the best I ever saw until today.
GunGrave is a anime adaptation of a game for the PS2 with the same name. The creator of Trigun is involved with GunGrave, which just adds to the awesomeness, but the storytelling is much closer to another classic, Berserk. Two men who grew on the streets as brothers join the mob to pursue power and a better way of life. The plot and the characters are presented little by little, so when sh*t hits the fan, you know exactly how bad it tranforms the world as the characters know it, and it's a big shock.

This is a very different title from your average anime, since its artstyle until the theme.
Kaiji is a hopeless punk who works at lousy part-time jobs and has no chance of a better life. To make things even worst, Kaiji gets the visit of a man saying his friend got a huge debt in Kaiji's name, so his only option is joining a series of dangerous gambling games to pay it off. Psicological games, where courage and inteligence are the key to win, and to survive. It's a very real approach of how money makes the world spin and can affect desperate people.

It was a huge shock to me when I realized Japanator had
Soul Eater out of its top 50 list. There's plenty of coverage in the first page, I thought it was one of the favorites among staff. Very well, Soul Eater is one of MY favorites, thanks to its superb style. The story, the characters, the setting, everything is so over the top you can't help but join the ride and have a good laugh.

What can I say about
Claymore? The animation is so beautiful you will think you are watching a OVA. When I first watched it, I thought it was another "generic girl with big sword fights monsters". Well, everything in Claymore is extremely well done, everything is there for a good reason. For example, just women can be Claymores, since men turn into monsters, unable to resist the power used by those half yoma, half human warriors. Claymore is about despair, in a world where humanity's saviors are half monsters, and even them can't protect the world of the strongest monsters out there. Great story, superb presentation. The only fault is the end, but you aways can get the manga to see what happens.
And here's a surprise! (Kinda of...)

Yes,
Hajime no Ippo is my favorite anime EVER. I included it in this list because it began in 2000, but the first series ended in 2002. New Challenger, which continues where the first stopped, had all of its 26 episodes aired in 2009. When some friends told me about Ippo, I joked saying something like "eh, I don't wanna watch a bunch of muscular, sweaty men". Obviously, I was almost retarded at the time. Hajime no Ippo shows how boxing can be complex, with very enjoyable fights, lots of estrategy and no special powers anywhere. The fights are really great, but the characters are not fighting all the time, and their time off are just as enjoyable, when the anime turns in one of the best comedys out there. The manga is still being released, and different from another animes that end before the manga, Hajime no Ippo leaves its end open, so we can aways hope for more adaptations into anime of this great series!
Wow, talk about wall of text! Anime is one of my passions and I will aways take a step further and be here to enjoy them and share the joy they can bring to any otaku's life! If you don't know some title from this list, go watch it, all of them are great!
