Anime, a distinctive form of Japanese animation, has been a global phenomenon for decades. These TV series and films span a wide array of genres and styles, making it nearly impossible to create a definitive 'best anime' ranking. Instead, this list focuses on the top ten most widely viewed and recognized anime, showcasing their widespread appeal and cultural significance.
10. Dragon Ball

Debuting in 1984, Dragon Ball stands as the oldest series featured here. It achieved immense popularity during its initial run and later inspired two successful sequels. While the modern reboot exists, it hasn't garnered the same level of recognition as newer anime dominating the industry today.
In essence, Dragon Ball and its subsequent series chronicle the adventures of young Gohan as he embarks on a quest to locate the seven mystical dragon balls. Later, the narrative shifts to his efforts to protect the world from numerous adversaries using extraordinary powers. As the story unfolds, characters discover methods to assist their allies even after death, occasionally returning to Earth temporarily.
Overall, Dragon Ball is a high-energy anime filled with extended combat sequences. It is particularly suitable for younger audiences and fans of classic anime styles.
9. Black Butler

A relatively new addition to the anime world, Black Butler has gained a respectable following, which it rightfully deserves. Following the conclusion of its initial season in 2009, a second installment of this supernatural dark comedy was announced.
The narrative centers on Sebastian Michaelis, a demon bound by a Faustian pact to serve Ciel Phantomhive, a twelve-year-old earl in Victorian England, in exchange for his soul upon death. While Sebastian embodies the ideal butler, executing his duties with precision, he also harbors a dark, sadistic streak. This is evident in acts such as trapping an unwelcome guest in a blazing oven or impaling kidnappers with ordinary forks. With its blend of dark humor and supernatural elements, this anime is undoubtedly a must-watch.
8. Naruto

While some might argue for a higher ranking, Naruto remains a globally televised phenomenon, with its sequel, Naruto: Shippuden, achieving similar success. However, the series primarily targets a younger audience compared to others on this list, which may render it less engaging for older viewers. Additionally, many characters adhere to typical shönen manga stereotypes.
The storyline follows Naruto Uzumaki, a young ninja, and his companions as they grow and embark on adventures, with Naruto striving to earn the title of his village's most renowned ninja. The series strikes a fine balance between intense action sequences and comedic moments, offering a more varied experience than Dragon Ball.
7. Hellsing

To put it simply, Hellsing exudes sheer coolness. Adapted from an ongoing manga, the series includes one main story arc and several OVAs. While the plot diverges slightly from the manga, the majority of the characters remain consistent.
Hellsing delves into the supernatural, focusing on the clandestine British Hellsing organization dedicated to eradicating vampires with the aid of Alucard, an ancient vampire. The series is packed with intense action and suspenseful moments. Despite its vampire theme, Hellsing is far from the typical teenage romance trend. Imagine an unstoppable, dual-wielding vampire with a penchant for obliterating anyone who dares challenge his masters.
6. Elfen Lied

Elfen Lied, a German term translating to 'the song of the elves,' evokes a sense of tranquility and beauty. However, the opening seven minutes of this anime are arguably some of the most violent in the history of the medium. Known for its graphic brutality and explicit content, these elements contribute significantly to its widespread recognition.
Another key factor is its compelling storyline. The anime introduces a humanoid species known as the Diclonius, distinguished by their two horns and invisible limbs called vectors. The narrative delves into profound themes such as morality, vengeance, and self-identity.
The intricate plot revolves around Lucy, a Diclonius who escapes from a research facility and finds refuge with cousins Khota and Yuka. They shield Lucy and her alternate persona, 'Nyu,' adding layers of complexity to the tale. To truly grasp the depth of this enthralling series, watching it is highly recommended.
5. Rurouni Kenshin

Rurouni Kenshin is perhaps most renowned for its OVA 'Trust and Betrayal,' which acts as a prequel. Set in Japan's early Meiji era, the series follows Himura Kenshin, a wandering former assassin seeking redemption by aiding those in need. The anime blends drama with moments of comedy, exploring the aftermath of war and the struggles of its survivors. Its depth and emotional resonance make it a must-watch.
4. Bleach

This ongoing series stands apart from others on the list, emphasizing themes of friendship and loyalty while blending action and humor. It features distinctive characters and remarkable growth throughout the story.
The narrative centers on Ichigo Kurosaki, a high school student who gains the abilities of a soul reaper to rescue his family. Tasked with defending both humans and souls from hollows, Ichigo later learns that the reaper who bestowed his powers faces execution. Determined to save her, he and his friends uncover a conspiracy within Soul Society, the realm of the deceased. However, numerous filler arcs detract from the main plot, diminishing its overall appeal.
3. Death Note

I must confess, I debated whether to swap this anime with the second entry on the list due to their stark differences. Death Note is a masterful suspense anime set in contemporary Japan, delving into themes of morality, justice, and the blurred lines between good and evil. Its intellectually driven characters and numerous plot twists keep the narrative unpredictable. While three live-action films were produced (including a prequel), they pale in comparison to the anime's brilliance.
The plot revolves around Yagami Light, a high school student who stumbles upon a supernatural notebook known as the Death Note, capable of killing anyone whose name is written in it. Light begins using it to eliminate criminals, drawing the attention of the police. The world's greatest detective, L, enters the scene, sparking a thrilling game of cat-and-mouse as both strive to outwit each other.
2. One Piece

As one of the longest-running anime series, One Piece unquestionably earns its place on this list. Unfortunately, the English dub by 4kids heavily censored many early episodes, though this should not overshadow the brilliance of the original anime.
The story follows Monkey D. Luffy, a seventeen-year-old with supernatural abilities acquired from consuming a mystical fruit. Alongside his eclectic crew, Luffy embarks on a journey across the Grand Line in pursuit of One Piece, the world's greatest treasure. Set in a richly imagined fantasy world, the series boasts unique characters and compelling story arcs.
1. Full Metal Alchemist

Full Metal Alchemist and its sequel unfold in an industrialized, alternate Europe where alchemy reigns as the pinnacle of science. The series explores profound themes such as morality, friendship, brotherhood, philosophy, and the principle of equivalent exchange. Blending light action, suspense, and humor, it offers a rich and engaging narrative.
Following a disastrous attempt to resurrect their deceased mother, the young alchemists Edward and Alphonse Elric embark on a journey to reclaim their lost bodies—Edward having sacrificed an arm and a leg, and Alphonse his entire form. Their path is fraught with moral dilemmas and emotional challenges, making this often poignant anime a gripping experience.
