So after 5 episodes of Season 7 and having seen nothing before here is my initial opinion on the cast:
Luann - reminds me of Adrienne from RHOBH. Seems like the leader?
Bethenny - What, exactly, is wrong with her? I could not handle someone who approaches
every conversation like they're on speed.
Ramona - seems like quite an evil woman and now her life is falling apart this combination makes me hopeful for great viewing. We stan.
Sonja - I can't decide whether I like her or not. To be honest I quite like her infallible perception of herself.
Carole - She seems like she's taken two basic facets of a personality - being lazy and a cougar - and tried to use it to cover up her true self.
Heather - I feel quite sorry for her, she seems too nice for this nonsense.
Kristen - I'm sorry I have no idea who this is.
Dorinda - probably my favourite

I also like her taste in chubby Mafia men. Ahem.
