Who murdered the mystery movie?

The Mystery movie, or even TV show, requires an investment in analytical thinking. Most programs on TV or movies made now don't ask for that, just that you sit back with popcorn or chips and go along with the ride. Many of them were replaced with such reality based programs as FBI Files, Forensic Files and the like. They are enjoyable and still require one to pay attention, often not revealing the criminals until near the end, and using "red herring" suspects. The police procedures are in full swing on these and still make for great viewing as they are factual.

IMO, the best fictional mystery/detective program ever was Perry Mason. Often several suspects, real killer revealed at the end, and great on police/legal procedures. After this comes Columbo and Monk, for me.
