The TVGN reruns were a positive sign, but this is a little better. Smart for CBS to do this now; it would have been better for them to do this last week (Duke vs UNC on Saturday on ESPN might be the only relevant competition). OTOH, it would have been meaningless with the Academy Awards the next day.
Anyway, CBS does not have to do this at all. Glad they are, and it's a perfect night to air the first two episodes in advance of the next several weeks where the show will air on time and not opposite great television.
