A very talented actor...
As a fanatic/DVD collector of "Criminal Minds", I was thrilled when it's spinoff "CM: Suspect Behavior" came out in 2011. It wasn't until then that I realized how many projects I've seen Michael Kelly in! As a DVD collector of ALL of the branches of the "Law & Order" Franchise, I was surprised to see that he had appeared on 2 episodes of the original 'mother-show', 3 episodes of "L&O : Special Victims Unit", & 1 episode of "L&O : Criminal Intent" (that episode 'Boots On The Ground' is, in my opinion, the best of the 10th & final Season. He seems to shoe up everywhere, & I think that he's an amazing actor. I would hesitate to say that he's underrated b/c of all of the A-List shows that he's guest-satrred on-some more than once. He turned in a very creepy role in the Season 5 Finale of "CSI : Miami" ('Born To Kill'). & he had a nice small, albiet important cameo in the thriller "Law Abiding Citizen".
I was very dissapointed that the 2nd "Criminal Minds" was cancelled, as 1) it was an incredible show, & 2)Kelly, along w/ the rest of the cast (Forest Whitaker, Matt Ryan, Beau Garrett, & Janeane Garofalo) for the Red Cell BAU Team really 'gelled' together. I look forward to anything else thast he does in the future.
