My opinion on fanfiction:The truth is I only prefer a strong main character because it is easy to make a character with a unique power or something interesting. I appluad any author who knows the value of a good character and developement. Part of that is showing the character's flaws but what a lot of authors on this site don't seem to realise is that you have to give the reader a reason to CARE about the character BEFORE developement otherwise why would anyone care if the character developes or not. It seems like people forget that you have to get the reader invested first and doing that is easier if you have something unique about that character that grabs the readers attention. If you introduce a character and then immediately have them fail then why should the reader care even if it IS a familiar character. I get that this is fanfiction but you can't expect that to immediately get the reader invested in your story you have to reestablish that connection.
