I'm off this week and am going to get a boxed set tomorrow to watch while I'm working on editing a local feature film I've worked on the past couple of months. So I know that I want one of these two series and in time will wind up with both of them. Locally the stores have both seasons of 24 but only the second season of CSI. My question then is do I get CSI and watch it without seeing the first season, I do not know if it is a season to season arc or not and if S2 will spoil S1 or not. OR Do I get S1 of 24 knowing if I like it I can go back and get S2? Thanks for all opinions!!!!
