I think the Serena trying to find her dad storyline though does give some insight as to why Serena used to be wild. It's common for girls who don't have a good relationship with their dads to seek this lack of attention in other men. Hopefully, the writers don't stuff up this storyline.
Also agree with Jkay..more character-driven, less plot-driven..all the other characters would also benefit from this. Probably even Vanessa and people would probably like her more. Although she's more of a supporting role rather than a protagonist, we hardly know anything about her so everything about her just seems really contradictory.
