"Team Shelby" - I like that! That's me, Team Shelby. I love this movie, I bet I have seen it 20+ times. The one thing that really bugs me is how M'Lynn just craps all over Shelby when Shelby tells M'Lynn that she is pregnant. Shelby tries all these different approaches to get M'Lynn on board, even going so far as to confess the marriage is having trouble, but M'Lynn just won't have it. Finally, when Shelby BEGS her to support the pregnancy, M'Lynn walks out on her. That is unforgivable, IMO.
Yeah, I get it, you are concerned about your daughter's health and all that, and of course it's all Jackson's fault, but how is your attitude going to help? Do you want Shelby to abort the baby? I doubt it. It's over and done with, being a b*tch about it is not going to help anything. I don't see how a mother could look in the eyes of a child who is imploring her for her love and support and just turn her down flat like that. M'Lynn is a cold, selfish scold who needs to accept that her daughter is an adult now and isn't going to do everything she says anymore.
Quite frankly I don't see how Shelby lets it slide like that, the next scene they are over a Truvy's and all is hunky-dory between them.
