Prue's love life...

Became pretty lame after Andy's death. First they build up this unusual romance with a guy who's basically her opposite just to have it end suddenly over something really stupid. After that she either has shortlived flings with bad boys or dumps guys left and right just because they're "boring". They actually could've done something interesting with the trauma of Andy's death and the fact that Prue always seems to take on too much responsibility when it comes to being a witch and protecting her sisters.
