Actually, the more I think about it, there's a reverse "Persuasion" going on if Sidney should be rich and available in a few years - having thrown her over and hurt her feelings, how would she feel about him and what exactly would he need to do to win her back?
I'd like to see a more mature, tidy-haired, less puzzled version of Charlotte who would really make Sidney work for her hand in marriage
Now, I could force myself to watch that, but only if there is a guaranteed happy ending. As it stands, I think they took a gamble on another series, thought they'd leave it open-ended but misjudged it. It's too downbeat - there's just no hint of hope. For a series that was largely, frothy, light and entertaining in tone, the ending is just too flat and pessimistic. It might suit a more modern drama with more serious overtones, but not this.
