Yes Teresa brings a lot to the show but I'm not that big of a stan on her that I feel the show would have tanked without her. Fans thought BH would tank without LVP it's #1 in ratings, people thought RHOA wouldn't survive without Nene it's still going strong. The only city that tanked after getting rid of OG's was OC and in my opinion 1. It only got good when Brooks came in 2. they let go of too many big personalities within 2 seasons
Teresa completely ruined the last season for me. I've seen blinds that Luis got her into anger management
For me it's a morals issue. If there were no fans, there would be no HW's and I don't want to be supporting convicted criminals... whether they are entertaining or not
