I've watched from the beginning. I've been a long time Mandy Patinkin fan (Gideon)... hmmm... since about 1987 or so (My name is Inigo Montoya, you killed my father, prepare to DIE!). When I found out another actor i like is on CM's I was sold, hook line and sinker. I remember watching the women's eye candy of the show when he was on Young and the Restless (Shemar Moore).
Not to mention, it's a well done show all around. They're more human than the 'cops' in other shows... When Reed was abducted and tortured by one of their unsubs, they kept the aftereffects of that experience through several episodes. he's *human* and they show that. They do that with all the cast. I like that a lot... it shows better writing... which is nice to see in Hollywood.
It's a great show... my other one is NCIS... my 82 year old father loves Abby, the Goth forensics tech... it's amusing to me.
