I think I can get used to it when all characters are recast. If it had only been Alexis, then it would be too weird. (Although Daytime soaps recast longtime characters all the time, which I am kinda used to).
I think I will be easily able to rate this show on its own merits. A reset version 2.0. Dynasty 1 and Dynasty 2, both beginning with Blake marrying a new woman that his kids aren't loving, but with 2 different casts and eras.
I will try not to have any expectations, just treat it as a new primetime soap.
