Well I have been disapointed in the lack of covered material with this series and always wondered how in the heck they will be able to end it when they are only doing like 10 episodes a year. This season is almost over already with only 3 episodes left. And the producers are talking about doing the last 2 seasons with a total of 13 episodes.
This kinda has me pissed off at the same time I was expecting it because how long can you drag out a series before the actors grow up and old and need to be replaced. I really don't think they will be able to wrap this series up in 13 more episodes. I'm expecting another of those shallow endings that happen to many tv shows when they suddenly find out its over and they only have a year to prepare.
