What really gets me is that there is so much real life Broadway drama that could be mixed into the show. It's as if none of the writers have ever worked in theater before.
I'm currently watching the tv series Slings & Arrows which is such a better show about the theater.
Whoever wrote about this being a woman's show is exactly correct. The show needs a shot of male testosterone to make it more interesting.
To fix this show:
Get rid of the Ellis character. He's poorly written and poorly acted and doesn't add anything to the show. At this point, why would anyone keep him around? That whole "Let's dial it back, I'll get you a car" was idiotic.
Ivy needs a real antagonist. There's nothing more interesting than knowing that while Ethel Merman is playing straight out to the audience, her co-star is standing behind her wiping his mouth.
There really needs to be a wisecracking character. McPhee should have been written in an Elaine Stritch or Shelley Winters template. She's understudying Ivy and doing another role at the same time. Of course, it wouldn't be McPhee playing it. To save the show, I would cut McPhee from the show.
If Marilyn needs a "name" bring in two male stars to play DiMaggio and Miller (see: Evita on Broadway). The two male stars can add drama to the show. Make one of them a pompous Nicol Williamson type.
There's really not enough material to make Debra/Christian interesting. I guess the show has to concentrate on their personal lives, but those characters have a short shelf life.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
