Just like it says on the tin: in the manga and the anime both, there are scenes, moments, events and whatever else you want to call them that people dislike. Each person has their own moments, and usually has several different options to choose from to explain why they dislike them. What I am asking is this: what events, from the manga or the anime, do you dislike because you feel that they are contrived?
Myself, four moments come to mind straight away:
-Akari's introduction in the manga. Not only does the character herself feel contrived, the fact she does more or less nothing after the chapters in which she's introduced doesn't help.
-Ryoga abandoning Anna Brown to go running back to Akane in the anime. This is especially potent seeing as how he had just admitted to himself that Anna is in love with him and he mightn't ever be this lucky again in his life.
-The Daikoku's agreeing that Akane won the Martial Arts Takeout Race in the anime. This despite the fact that Kaori lost only because Ranma-chan semi-cheated (she was partially forced by Genma) and intervened in a race she had no business participating in.
-Ranma-chan appearing just in time to win the Tendo Dojo back for Akane in the second half of the One To Carry On OAV. Especially seeing as how he, last we saw him, had apparently finally gotten sick of the Tendos and was getting his stuff together to leave town.
