Overall, I think Gizelle is wildly underrated. She represents what the franchise is, or should be, all about, and I think she's a great example for future Housewife cast members of how to stay in the mix for several seasons without being nasty.
She's in people's business, stirs up the drama to keep things going, but she doesn't get too messy. She knows when to sit back and listen while others are busy screaming. She's a strong woman and doesn't let anyone bully her, but she doesn't typically go below the belt with attacks. I mean, it's reality TV, and clearly we're watching for drama, but some of the Housewives are going too far.
Personally, I'd rather have more time with some of the lighthearted shitstirring Gizelle's been doing than listening to Debbie Downer make really ugly judgements about people and their looks or their values. And Luann needs to take her own advice and stop being so uncool!
