Back on topic- I think that Broadway is where Heather belongs. It's her element- and where she shines as a star. She shines on Broadway because of her talent, but she won't shine in the pop world because of her talent. Broadway wants talent like Headle has. There's no doubt about it that she could be very successful if she decided to come back to Broadway.
Just as I choose not to judge you from the one reply you just gave me, please don't judge Heather on the one experience/run-in you had with her. Surely you know actors/actresses are only human and have bad days just like everyone else.
