Sure everyone adores her redemption arc, that starts at 7 hearts it feels like, but until the extremely delayed redemption arc, she's nothing more than cold, rude, and in my personal experience, shallow. Her being friends with Alex doesn't help her case(though it doesn't hurt it either, considering it's pretty much irrelevant) but that friendship just serves to feed more into the "stupid jock hangs out with pretty mean girl cheerleader" aesthetic (I'm aware Alex gets much better too, and starts on the higher path sooner even than Haley, but I also have emotional cutoff to either of them because of the schools I went to funneling all their budget into boosting the moot point of football and basketball. The only redeeming points of Haley imo are liking sunflowers, liking photography, and by the time you e already married her, her finally coming around. Personal experience, she's just more trouble than she's worth, by about a mile
