Yeah, but there's no reason they can't change their mind.
I am well aware of Sharon having her own merits, but some people are just unwilling to view it objectively.
And her being related to Peggy does complicate things, in that you need to show Steve developing feelings for her without being aware of who she is related to. Which is a bit hard because who's around someone long enough to love them without asking what their full name is?
Or you need to show Steve finding out and reacting, and then have time to take it in, react, and have the story proceed in a way to justify them falling in love. Which would take time and would have been easier if
Natasha just told him her full name.
In related news, I was indifferent about EVC as Sharon, before and after seeing the movie, and to be honest wouldn't mind her being recast.
However, wow
