I am happy to report that I am now an alumnus of 24, having watched the third season from this pack.
All in all, 24 is an awesome TV production, full of suspense, speed, good acting, high drama, tragedy even, heroes, bastards, in-betweens, surprising turns at every corner, nice gizmos. I could go on ... oh, and the special features are really good & surprising (they invented their own virus). Nice quote: "Our fast food chains are weapons of mass destruction!" says one expert on communicable disease.
