Final verdict: a big MEH for me.
The FL was a big fat liar/traitor for way too long in this show to allow you to be sympathetic towards her as the FL. The truth of the matter is that even if her company wasn't bad/whatever, she still was willing to do anything (even dirty stuff to hurt reputations/business/etc) in order to get a promotion. She just wasn't a good person to begin with. The only reason she was sorry later was because she had fallen in love with the ML. If she hadn't "cared" about him, she wouldn't have felt so guilty. Which means she would have done the same to someone else.
The FL's over the top fashion choices also severely distracted from the good points of the show and painted her in another unflattering light making the watchers/audience distance themselves from "connecting" with the FL on any level. You can be different & unique and have your own sense of style but the show went overboard to the point of alienating the FL from her audience IMHO.
The ONLY redeeming quality in this show was the ML. I can watch him in anything *SWOON*
