I previously owned seasons 1-12. I avoided season 13 as the reviews of it (even from fans of the series) thought it was distasteful. I did order 14. I found it lacked a lot of the drama and depth that the earliest seasons had, but it was nice to see the characters back again. We all get older, right?
As much as I love the series, and I always will, I think it's time to call it quits. To keep popping out episodes at some point, just seems like a desperate act just to "keep going" and it shows. If you are a fan of this great series as I am, then I would recommend getting Season 14 to add to your collection. However, if you aren't attached to the characters and haven't seen the show before, this is not a good place to start!
