This isn’t a good show at all – and even in an era of reboots, where we just brought Roseanne back, this modern Dynasty doesn’t have much of a purpose. But way back then, the original Dynasty on ABC didn’t have any oomph until Joan Collins joined the cast and shook things up as Blake Carrington’s bitchy ex-wife, Alexis. And in tonight’s new episode, called “Alexis Returns,” that character makes her first appearance in this new series version – played by Nicollette Sheridan. And in a nice nod to TV’s past, she makes her entrance as Alexis wearing an outfit patterned after one of Collins’ early Alexis showstoppers.
