A lot of changes impact the Las Vegas crime lab in this most recent round of the internationally popular CBS series. Two are evident right off the bat, as Ted Danson - playing the new chief - and Elisabeth Harnois, seen previously as a guest star, become cast regulars.
The other big switch happens midway through the season, with founding co-star Marg Helgenberger departing and Elisabeth Shue ("Leaving Las Vegas") joining shortly afterward. *** (Not rated: AS, P, V)
