Scrubs is they best show NBC has and they have not even annonce a return date.
Never cared for scrubs. Las Vegas is OK, but it's on at the same time as 24 so I only watch it in reruns. Medium is pretty good. The Apprentice is the only reality show worth watching. That's about it for NBC primetime for me.
Aside from 24 the best shows are on cable. I love Rescue Me on FX. The Comeback and Entourage on HBO are good. Not a whole lot else out there that I ever make it a point to watch.
