>>95922761>Beating a character down until they collapse is a terrible way to address flaws, or introduce them for that matter. It didn't work in LOK, and it won't work hereThat's not at all what's happening with Star.
Her most glaring flaws are apparent from the start but so are her virtues. She's able to reconcile with Marco because she recognizes that she's being unfair and overbearing toward him, and offers to leave even knowing that failing to integrate on Earth might cause her to get sent to reform school.
Even later into Season 2, while Star's problems and hardships continue to pile on and start affecting her more personally, she is not being broken by them. Star learns best through adversity, being faced with an obstacle she's told is impossible to overcome and putting everything she's got into pushing through it anyway. The more that is taken out from under her, the more she is forced to mature and grow to rise back up.
Her "suffering" seems unusually brutal for the medium because her progress is steadily built up over entire seasons, rather than being accomplished as the moral of a single episode and promptly forgotten at the start of the next.
