The characters were interesting, the acting was decent, the cases were definately exciting and were much more involving than some seen on CSI to date. OK, sometimes the cases were a bit too far fetched but that's hardly a fault worth cancelling it over.
I watch quite a few crime shows and this stood out as one of the more interesting ones for me - I think they got the balance between cases and characters just right. The casting was good too - I loved Hale's gruff voice, it matched the character's personality perfectly.
I just don't think it was given a fair chance to prove itself.
