Yes, Ebersole was completely miscast, she never came off as diva-esque enough or larger-than-life enough to be Margo Channing. Donna Murphy or Bebe Neuwirth would have fit the bill better.
Still, you were always aware that this is just not a good show. It's not bad but it's mediocre at best; the songs are pretty generic (save for a couple) and at no point does it ever reach even remotely the brilliance of the ALL ABOUT EVE screenplay. There's no sense in reviving this, really.
I do wonder who they could get to star in this.
