I'm not really a fan of TV crime shows, but new series always give me the chance of experiencing some fresh air - so I check them out. In this case, I was glad I did. The pilot started off slow, but after about 30 minutes (it was 90 minutes total w/commercials), it actually became interesting and stayed that way to the end. Subsequent episodes have kept up the momentum.
One novel aspect of the show is that its about a lady marshal in Albuquerque, New Mexico. She's in charge of people in the "witness protection program" who have been assigned to her area. She cautions and reassures them that since 1970 (when the witness program started), "No one who has followed the rules has ever been harmed." Powerful words.
Can they comply? When things go wrong, can she protect them? How can she keep their identities safe - even from the local police?
Aside from the setup, the show is ultimately interesting because she's fun to watch. She's sassy, witty, playful, smart, responsible ... and physically tough. I recommend watching an episode; if the lead character grabs your interest, then you're likely to enjoy the show.
