The show really started off well, interesting premise, good story lines through seasons 1-4. Then Season 5 happened and sucked the life out of the show. It's as if everyone decided to go on some sort of hiatus and the show just bottoms out at that point. What were they thinking? It's no wonder that the series was abruptly cancelled after Season 7. I guess the network was afraid of another Season 5. Never could understand the point of killing off the Abby character!
