I am just getting into Criminal Minds now, but if you enjoy crime dramas that push the envelope, you'll enjoy Unsub. Criminal Minds took a lot from Unsub, the terminology, the private jet, the criminal profilers, and it worked. I think at the time, Unsub was a little too raw, sadistic killers, child murderers, etc. and I wish it would have last longer, but if you find it on DVD, its worth your time. It was a dynamic cast of varied actors, each who brought something different to the show, the married couple who were both CSIs, a primadonna profiler who could adopt their mindset as easily as putting on a pair of shoes; an ex-cop from the old school; a timid yet caring investigator who always tried to help and a determined, self-sacrificing leader.
