Good idea, well photographed, but needs new material Cold Case is one of the best new series to come out of CBS this fall. The basic idea of investigating old, unsolved cases is a good one; it's a surprise that no one thought of this earlier, as there have been shows for years on A&E and other cable networks showing how actual cold cases have been solved. A nice twist is that the cases they investigate really are old ones (two recent cases went back to 1973 and 1964); one thought I had when I first heard of the show's concept was that they would only portray cases that were going to be a year or two old, leading it to be just another detective show. Having the cases go so far back allows for a lot of camera magic, showing people how they looked when the crimes were committed and then how they look today; some viewers may find this annoying but I think it is an effective way to show how much time has passed in the story. Going back many years also allows for the use of lots of classic songs and nostalgic clothing and hair styles, which I'm sure brings back memories for many people.
As other people have said here, the main drawback in the series is that every episode seems to tell a story that you know you've heard someplace before, either in real life or in movies or books. The premiere episode, though well told, is quite obviously a re-telling of the Skakel murder case; anyone who even saw the promo for that show could tell it was derived from that case. The other shows so far also seem to have familiar plots, but are still well produced; hopefully some new writers will be added to make up some original stories before viewers start getting bored.
Kathryn Morris really shines in this show as Detective Morris; she's smart, dedicated, tough at times, and attractive. As she is the only female homicide detective in the department, the show could have had a crusading feminist sort of theme, but this is thankfully not the case. The rest of the regulars are excellent as well, as are the supporting cast each week.
Overall, I would give Cold Case a 7.5 for now; it could how higher or lower, depending if the writing becomes more original in the future or stays somewhat derivative.
