I picked 24, Prison Break, and the Office. I stopped watching Heroes about 3 or 4 eps into the 3rd season, and haven't really seen the others besides CSI.
Although, my favorite shows are 24, Chuck, and Friday Night Lights.
"True Blood" (2008) wins going away. "Greys Anatomy" (2005) places. "Castle" (2009) to show. "House M.D." (2004)
I'd heard that "The Unusuals" (2009) was not picked up for this fall, unfortunately.
