Numb3rs (Fridays at 10/9c, CBS)
Issues: The show's episode order was chopped drastically to make way for newcomer Miami Medical. Creatively, the show's season finale felt like a good-bye, and series star David Krumholtz has already landed a gig in Ron Howard's IRS comedy pilot at Fox.
Considering that Nick and Cheryl (the show's creators) called the season finale "probably the last episode of the series," I think that's a pretty good indication that the show has run its course.
It was one of my favorites. I guess I'll be pulling out my DVDs and re-watching it this summer.
