Fandom frequently classifies Clara in s7 as flawless, characterless, or simply a generic Adorably Spunky Girl. I disagree with this description, and believe the problem lies with the observers rather than the text as given.
Exhibit A: The final gif is a moment that frequently appears in collections of funny Clara lines.
In context, the TARDIS has just explained that if she helps Clara, it will die, to which Clara responds: I don’t care.
Fandom classifies this as ‘cute’.
Also the fact that the one person that the TARDIS knows she’ll most respect is herself. That is not flawless or characterless, and is, in fact, really interesting.
