I think what can be over looked with Jennifer, is that her 'team' is/was some of the best in the business. During the Bennifer-era she sacked a lot of that team, including her long-time manager Benny Medina. Ben Affleck tried to get rid of Benny as he was ever present in their relationship (including going with them on romantic getaways) so there was conflict there. After Ben left her pretty much at the altar, she retreated, met Marc, and Marc encouraged her to live a more protected life, avoid paps etc. By the time she wanted to reintroduce to the world with Rebirth, I don't think she had the right team in place. It felt like it just came out and not enough ground work was done before hand. Get Right (which now is one of her signatures) was too jarring for the US market and radio was unsure of her. A horrific second single choice killed any momentum. She tried it again with Brave, but label changes meant she knew no one there, and she wasn't a priority, being pregnant also signified the early end to that era. I think once she got back with Benny (once he handed his notice in to Mariah of course...) he really formulated a plan for her to regain some status. She was performing a lot more after the tour with Marc, I think she regained a lot of confidence, and she was performing at events she probably would have turned her nose up to earlier on, putting the graft in and honing her skills (random Pride events, that 7 world wonder medley event etc). I think the right risks were made (American Idol) and the stars aligned with On The Floor. She's never took her foot off the gas since then which I really admire and she makes it so easy to be a fan. My worry is her being back with Ben...although I think she knows she's in the driving seat career-wise now.
