I compare this show to Law & Order: SVU. SVU BEATS IT IN EVERY WAY!!
First, I don't like the acting on CM. Way too melodramatic for my tastes, especially the older gentleman with the goatee. There's constant melodramatic music playing throughout, which makes the show feel like every moment is an earth-shattering moment in their lives.
Every episode of the show is basically a mini horror flick, with all of the clichs you might expect.
I find the shows to be too predictable. Unlike Law & Order, you don't get to see how the trials of the suspects pan out, so you basically have to believe that these profilers are perfect in every investigation, all the time. Not very realistic, IMHO.
Also, murder cases are often not open/shut cases. We see many examples of this in real life (OJ Simpson, Casey Anthony). There are many blunders that occur during police investigations and prosecutions that complicate the outcomes of them. This show encourages people to believe the profilers are accurate every time.
