Since TV shows are careful about moving cities mid-series now, we think shows with spin-offs in different cities should count in this category as well. CSI spawned two very successful spin-offs with very different looks and tones from the original show. But, with so many iterations of the same franchise out in primetime programming, do you ever feel like you're suffering from CSI overload? Or are you ready for a fourth city?
