Hum... I expected a stronger Alexis, closer to the "Alexis concept".
Elaine Hendrix is a good actress, no doubt about that. But Alexis (both Joan Collins and Nicollette Sheridan's version) has something of a diva, very opera like (I guess the "opera" in "soap opera" is on purpose). She's supposed to be somewhat emphatic and Joan Collins played upon this silent movie way of acting, very expressive, very drama queen. Nicolette, via her long love story with soapy dramas, got that "campy" way of acting (Michael Michele does have this touch too and she happens to become my favorite character) and I think it involves a slower (hence stronger) kind of delivering your lines. The way you act on stage, well sort of, considering the fact you're in front of a camera.
I don't know the résumé of Elaine Hendrix, but Joan Collin being first and foremost a stage performer, she knew perfectly how to build this iconic and bigger than life character, working out every detail. As far as I'm concerned, Dame Joan Collins is a surgeon. Nicollette Sheridan could have done the job too (if only she had been given a better stuff to root for...). She carries this intrinsic quality (is it?) of campiness in and off screen (you can't buy it, it's a gift of Gods).
A soap like Dynasty needs to be overacted. That's rule number one. The big tree of fantasy needs to hide the forest of reality. But this reboot (which I watch anyway, in spite of myself, trapped in nostalgia) doesn't work. It does not. Writing, cast, whatever, something doesn't match.
Well just my two cents...
