I also find it amusing how the haters never point out the flaws in Iris, they simply state they hate her and are done with it. What more proof does one need of mindless hate?
She is hated for reasons. Hate and love wouldn't exist without reasons and facts.
To sum it up quick:
- She was the second female lead with a second type master goal and that type of goal is flawed to be a goal in the active on-screen part of the series.
- The goal went nowhere. There wasn't even any competition to prove her strength as potential dragon master like Whirl Cup was to Misty. Instead Clair and Drayden appeared. Two regular gym leaders Ash could defeat.
- With that she was pretty much the girl with the least amount of focus on her goal. The three previous girls already were competent enough in battles, especially Misty. And since the focus is on Ash the whole time in terms of battles, she had no particular reason to be in the series except to play the obligatory female protagonist for the quotes.
-Nostalgiafags defends Misty because of that simple reason: Nostalgia. Iris doesn't have that. Her gag was annoying to many people and she seems to can't take any critic to the same argument.
I am not an Iris hater myself and no BW hater in generell, but I can understand the critic. She got development and there are many good and emotional scenes with her, but she had many flaws. She was one of the least popular even in Japan.
