If you think Meredith Grey and her colleagues can be unlikable sometimes, just wait until you meet the title character of "Nurse Jackie." The dark comedy centers on Jackie, a stressed-out nurse working at a New York City hospital, dealing with said stress with a disastrous personal life and a substance-use problem. She's not the only one in her department with issues hidden beneath the surface; pretty much everyone, from the seemingly perfect doctor to the perky new nursing student, has something going on that they're not admitting. It's a spikier dark comedy, as opposed to a soapy drama, but it definitely shares a lot in common with "Grey's" when it comes to probing the complexities of the medical profession.
