Plot can have similarity with other cop shows, but I think actors are quite successful with their genuine performances. Action, investigation, revenge, romance, emotions and humor are all inclusive. I think it deserves more ratings.
Sullivan and Romba have interesting backgrounds. We can learn more about their past, as the series progress I hope. Sullivan is a beautiful cop, yet she does not thrust and get close to anyone easily. Romba, on the other hand, has some numbers of tricks, he is very clever, honest and charming taxi driver who becomes sort of an assistant detective.
In the pilot other characters include a captain, a special agent, a mom, and a child who spice up the show altogether. Captain is a father figure and protective. Special agent is obsessive and jealous about his work, Romba and Caitlyn. Mom is supportive and child is a good son.
There is no offensive language. It is suitable for families. Lastly, I think the series should continue so I rate it 9/10 to support the effort of these talented crew.
