The whole thing reminds me of Farrah Fawcett, she had the media world by the tail, and made some selfish personal choices that plagued her the rest of her career. I really didn't see her as a leading part in the others. And don't see her removal as a detriment to the movie or concept. I went for the action and tech of the movie. And really feel it just detracts from why I like them. Non stop action and mayhem. I don't want to pause the flow of those aspects to have "chick flick" elements slow it down.
Doing that with success takes a good director, and one who can keep people in line with the script, concept, and budget. Guess Megan learned the hard way. I'm sure she will find her way out of it. Hope she does and doesn't continue the "it'* all about me" attitude. Maybe she should reflect what that earned Farrah.
