This show has potential. The shades of blue in the title refer to the shades of moral quality found in the main characters. Jennifer Lopez and Ray Liotta both play corrupt New York City cops. Despite being corrupt, they are both cops and do their jobs, even if they stretch to law to do them. The FBI discover that Lopez is corrupt and coerce her into trapping Liotta, so they can bust him. Reluctantly, Lopez does as she’s told because she doesn’t want her daughter to grow up on her own while her mother is behind bars. Lopez is always busy. When she isn’t trying to trap Liotta, she’s fooling around with other women’s boyfriends. Another one of her shades of blue morality. Ray Liotta is volcanic as the corrupt cop with an explosive temper and keeps the show interesting.
