So when Damon is willing to murder, maim and do whatever he wants to anyone if it means a chance to save Elena, it's noble. But when Davina accepts a position as regent to bring her dead boyfriend back to life, it's a shallow priority. Wow.
So what if she's young? Would you not hate her if she was 22 and not 16? No. You only hate her because she doesn't take crap from no one. She's a badass character who has the power to save and protect herself and those she loves, and uses it without harming anyone. She's loyal, friendly. She's the best character in both shows, and if you can't stand her for all her good qualities just because of her age, then she's not the problem.
Show me a good reason to hate her, and I might agree. Or agree to disagree. But when you show her age as a reason to bash her personality, her decisions, the things she does; when everyone else who's done shallower things get a pass, then your opinion doesn't worth a dime to me.
