Opinions on Twilight Sparkle

Well, don't take this for granted but I actually kind of dislike Twilight Sparkle.
Her personality about being a bookworm and being pretty agitated in terms of personalities in media, is overrated and I kind of wish that it could've been changed.
And not just that, the fact that she also would disrupt or change anything and anyone for the pure validation of Princess Celestia (i.e. the letter episode with Twilight) is clearly weird and not okay.
She's a good learner and is pretty logical, but she needs to calm and step down.
