She comes across as conceited to me and sort of over-privileged, for lack of a better word. I like a few of her songs (Blue Jeans, Dark Paradise, Video Games) but was disappointed overall with her album and, while she's improving, her live performances are just lacking for me. ATRL's bandwagoning of her is also kind of irritating but I guess I can't blame her for that. She's still got time to win me over though, unlike some others
As a side note, the thread title is sort of misleading. Most people would assume that if you "rate your hate" that rating someone a 5 means you have some level of hatred for them, but that doesn't seem like how most people are voting. According to the OP, if you hate them you should vote 10 and if you love them you should vote 0, but what of you're completely ambivalent to them? A 5 seems harsher than it is according to the OP. It's a minor point and I'm rambling and on mobile but hopefully some of that made sense
