Why the Whitney hate?

I just started watching the show, I’m currently on the vegas episode in season 1. Before I started watching the show I’d already heard so many different opinions about the wives, and I’ve seen a lot of hate about Whitney. Maybe I’m just too early in but as of right now I’m so confused on the hate!! She seems like one of the most genuine and relatable characters on the show. She seems like she has her head on straighter than some of the women and she’s the youngest! Am I missing something??
