I know how you feel. I worked my way through all the seasons of NCIS and got caught up for the season premiere (and I got my roomie hooked).

Then, I started going through MacGyver and Highlander but I only made it to second season on the former and mid-season one on the latter before class got in the way. It's exhausting.

I think I've probably stayed away from the CSI franchise because it has so many spin-offs and I'd be tempted to jump into all of them. Which, *dies* would kill me.
