Worth a look if only to see how it was done in 2001. Undercover cops with personality, Garth O'Hanlon (played by Stephen Tompkins appearing in nine of the of twenty-two episodes in the complete series) does a nice line in asides.
I thought the Jekylls the best episode. The writers made much more of the plot: drugs; guns; counterfeit goods. It had more of a realistic flavour than Untouched episode. That, I thought, was rather pedestrian though it had the great Ian McShane enjoying himself (though will he ever better his Deadwood role).
As these are cop shows they have to follow the formulae of involving plenty of cars, talking while standing by them, getting in and out, driving them in traffic so they go across the screen left or right and ideally a chase somewhere that provides action but doesn't need dialogue.
`In deep' isn't one of the greatest cop TV series but it does supply all the ingredients for an entertaining hour per episode viewing.
