The anime's ending was indeed quite abrupt and left many fans feeling disappointed. This is because the anime diverged from the manga's storyline and created its own original ending. In the manga, Ranma and Akane do not get married until much later in the story, and their relationship is much more complicated. The anime's ending also left many plot threads unresolved, such as the mystery of Ranma's father and the fate of the other cursed characters.
Despite the disappointing ending, the Ranma 1/2 anime remains a classic of the genre. It is known for its humor, action, and memorable characters and is still enjoyed by fans around the world.
