If someone has a POV, fine. I don't think every show needs a POV - and I wish the FN wouldn't require that.
I think a lot of viewers watch shows because they like the host and what the host cooks. Russell has made some excellent dishes and I'd like to watch him cook what he likes to cook - not have him struggle to fit recipes into a deadly sins POV or whatever his other POV is. I'd watch if it was just Russell's Kitchen.
I'd watch Demaris cook (at least until her cutesy talking to the food gets too annoying), but I don't really want to watch a show about Southern cooking. Let her have a Cooking with Demaris show. There will be a Southern influence on many of her dishes because of who she is and where she lives, but don't force it.
I don't find Stacey fake. She's won a lot of challenges, so she can apparently cook. I like her POV of updating old classics. Some of what I cook in my food repertoire could use some updating!
I'd watch any of these three's shows to see if I like them. If Rodney wins, my inclination would be to not watch his show, but I'd probably tune in to see if his producers were able to at least get him to speak clearly.
