You know, I felt as though it was the best episode of the season; but I felt like the end was "tacked on". Really, if there was ever a fitting moment to end the series on, it was those two getting married and taking over the BuyMore "We're out". I thought that was the best possible setup to close right there and say "thanks for four great years".
I realize it's been renewed, but I'll say that I found this last season really uneven; the setup for next season looks as though it was a last minute hail mary against a great backdrop to close it. I'm hoping this isn't like a Buffy Season 5-Season 6, where Season 5 had probably one of the best potential series closers out there; and Season 6 had to claw it apart..
