Fairy Tail

Fairy Tail is a 2009 anime adaption of the 2006 manga of the same name.

Plot
A celestial wizard named Lucy Heartfilia meets Natsu Dragneel, a fire Dragon Slayer wizard, who is trying to figure out what happened to his foster father, Igneel, and Happy, a talking blue cat that can fly. After the meeting, Lucy is then kidnapped by a Bora of Prominence, who was pretending to be the Salamander of Fairy Tail, to be sold as a slave. Natsu rescues Lucy from her kidnapper and reveal to them that he is the real Salamander of Fairy Tail and uses Dragon Slayer magic, which is a lost form of magic. Natsu offers Lucy a membership into the Fairy Tail guild which she proudly accepts. During the anime, they go on various adventures along with other members of the same guild such as Erza Scarlet, Grey Fullbuster, and Happy.

Why It Rocks

 * 1) Very nice animation and both the first (2009-2013) and second (2014-2019) art styles look good.
 * 2) *Also, it's nice that the earlier episodes of the anime used a different art style compared to the manga, which clearly copied One Piece's art syle.
 * 3) Exciting and face-paced action sequences.
 * 4) There are a lot of loveable and memorable Heroes here
 * 5) *Natsu Dragneel is a reckless and hotheaded (pun not intended) Fire Dragon Slayer Wizard, the son of Igneel, and the younger brother of the Dark Mage, Zeref Dragneel. Ever since the day that the dragons disappeared (July 7, X777), he (along with Wendy and Gajeel) spends the majority of the anime trying to find out what has happened to his foster parent Igneel, which later is explained in the Tartaros Arc. In the Alvarez Empire Arc, he was revealed to be E.N.D., a very powerful demon from the books of Xeref.
 * 6) *Lucy Heartfilia is a kind and caring person in the Fairy Tail guild. After the death of her mother, she left her life as a Heartfilia and her father to b follow her own path of independance. She genuinely cares about her Celestial Spirits as she did things for them during the Celestial Sprit Arc, as wel as her guild.
 * 7) Most of the characters have interesting abilities and it's fun to watch them use them in battle.
 * 8) Some of the character introductions are interesting. Examples include:
 * 9) *The scene in the first episode that reveals that Natsu is part of Fairy Tail is epic.
 * 10) *Wendy Marvell's introduction is cute and chilling.
 * 11) *Zeref's introduction is incredibly tragic as his shows his caring nature unintentionally killing plants and animals.
 * 12) Some cute characters like Happy, Carla, Pantherlily, Frosch, and Kemokemo.
 * 13) The characters have good chemistry, for the most part.
 * 14) There are a couple of funny running gags here such as Grey taking off his clothes in front of people, Natsu's motion sickness and the iconic WOW sound effect.
 * 15) Memorable and unforgettable lines such as "I got a fire in my belly!", "REQUIP!", and "Open! Gate of the (celestial spirits), (Celestial Spirit's name)".
 * 16) The villains are very interesting and cool, with examples such as Jellal, Acnologia, Oración Seis, and especially Zeref.
 * 17) A lot of the characters have interesting backstories:
 * 18) *Zeref Dragneel's backstory stands out the most as he has to most tragic and devastating origin, which lead to him being misunderstood by almost everyone. This backstory makes him incredibly tragic and sympathetic.
 * 19) In the Zero Arc, we get to learn more about Mavis Vermillion as well as how she founded Fairy Tail.
 * 20) There are some sad touching moments such as when Zera was revealed to be an illusion and Lisanna reuniting with Elfman and Mirajane.
 * 21) Memorable and catchy openings such as "I Wish", "Fiesta", "Rock City Boys" and "Snow Fairy".
 * 22) All the ending songs are nice and the chibi art style used in the earlier episodes and the last season look cute.
 * 23) A lot of the villains such as Jellal, Ultear, the Oración Seis and Leon later become allies of Fairy Tail.
 * 24) Nice combination: The Female Humans being sexualized didn’t stop from them being very competent, skilled, and resourceful fighters, completely on par with the men.
 * 25) Having an abundance of powerful women doesn't come at the cost of making the men weak, stupid, or spineless.

Bad Qualities

 * 1) Some unlikeable characters such as Laxus (though he gets his comeuppance at the end of the Battle of Fairy Tail arc and becomes less egotistical and rude), Ichiya and his Edolas counterpart, Nichiya, Aquarius, and Karla.
 * 2) *In the Keys of The Starry Sky arc, there's a group of characters called the Jiggle Butt Gang. If you guessed by the title, they are a group of three characters with extremely large buttocks that only exists to shoehorn in fart and butt jokes, not to mention the hideous character designs too. After the aforementioned story arc, the Jiggle Butt Gang doesn't appear again and their disappearance isn't explained nor it is acknowledged by the characters, thus leaving a plot hole that'll never be resolved. And even in that arc, they were only in three episodes.
 * 3) **Though in episode 327, it was revealed that the Jiggle Butt Gang were fine after all when they appeared as a non-speaking role.
 * 4) *Elfman can be annoying since he says the word "Man" in most of his lines.
 * 5) **Ichiya is another character who does the exact same like Elfman
 * 6) *Juvia can be unlikable because of her creepy obsession with Grey and constant third-person speaking, to the point where she stalked him a few times while he was doing a job with Natsu and the others.
 * 7) *Sherria Blendy is a Mary-Sue.
 * 8) Speaking of story parts, there are a couple of them in the anime that were confusing such as:
 * 9) *How did Zeref, The Magic Council, the Grimoire Heart guild and even Acnologia were able to find and access Tenrou Island, despite the island being impossible to find for outsiders, and can only be accessible to those that are apart of the Fairy Tail guild?
 * 10) *When Mavis went to explore some underwater temple, how did Yuri and Warrod know where she was even though Zera was unable to tell them and that they can't see her due to being an illusion?
 * 11) *How did Silver Fullbuster know who Ul was and that she sealed Deliora away despite being dead before his son, Grey, met Ur.
 * 12) *When Makarov was about to be killed by Xeref before being rescued by Mest/Doranbolt, how did Mest know where Makarov was in the Alvarez Empire arc,
 * 13) Mystogan (Edolas Jellal) was poorly utilized in the series, which is really disappointing since he has a very interesting backstory and a interesting character in general.
 * 14) While most of the humor is good, some are unnecessary and they come off as more jarring than hilarious.
 * 15) Compared to the manga, the anime's action scenes aren't as intense as the violence was toned down.
 * 16) It overuses the fake out death trope.
 * 17) Formulaic writing as almost all of the story arcs have a similar story structure.
 * 18) It overuses the "Power of Friendship" cliche.
 * 19) Despite having a good number of well made redemption arcs, a majority of the show's villains are given, depending on your opinion, rushed and undeserved redemptions (Ultear, Meredy, the Oración Seis, Flare Corona, Minerva Orland, the Legion Corps, etc) mainly to avoid killing and continue the message of redemption and forgiveness, but some viewers would consider them to have came out wrong. Of course, your mileage may vary.
