User blog:Kintobor/This episode, Down To The Fiery Finish, is the most infamous episode of anime

This episode faced huge criticism from fans when Ash lost the Kalos League against Alain. The fans severely criticized the episode due to misleading trailers that suggested that Ash would win the battle and because Ash had lost all of the Pokémon Leagues in past seasons. Fans also disliked the outcome because they believed Ash's Greninja had many advantages over Alain's Charizard, including the fact that water-type Pokémon are capable of critically defeating fire-type Pokémon, and that the rare Bond Phenomenon Ash's Greninja was subject to was said to be much more powerful than a conventional Mega Evolution. Several animators of the series were also disappointed that Ash lost. A Change.org petition asking that an alternate ending be created in which Ash wins received more than 3,900 signatures.

If you want to know my opinion, I fully agree with angry fans. They had/have full right to be outraged/irritated/angered/enraged. Many trailers suggested that Ash would win, which made fans very hopeful due to the fact that Ash lost all previous Leagues. However, when Ash lost Kalos League, their reaction was fully rational. All of their hopes and joy were literally nuked within one moment. Even some animators were unhappy. And I think this alternate ending where Ash wins should be created. This should be a real ending because this time Ash really deserved to win. Ash's victory would make much more sense than Alain's. The fans are not butthurt and they were not overreacting. I think that this episode's makers/writers should have been sued for misleading fans.
