Nurse Jackie just keeps getting better and better

"Nurse Jackie" just keeps getting better and better. Season Four of the show is by far the best season to date, and that's saying a lot. This season, Jackie (Edie Falco) is reeling from her breakup with Kevin and her self-admission of being a drug addict. She finally (albeit grudgingly) begins taking responsibility for her past behavior and enters rehab while fighting to retain custody of her two kids. Meanwhile, big changes are underway over at All Saints as Bobby Cannavale joins the cast as the high-strung control freak Dr. Mike Cruz, the new head of the hospital who shakes up the E.R. and becomes a major thorn in everyone's side, especially Jackie's. The supporting cast members all enjoy great storylines as well. O'Hara and Zoe make big decisions about their personal lives, Gloria and Eddie are forced to make some big changes of their own, and Thor is has some of the funniest one-liners of the season and never fails to steal the show whenever he's on screen. Perhaps the one shortcoming of the season is the show's under-utilization of Coop, who doesn't have much of a storyline this time around. Still, the other fabulous elements of this season compensate for that, in my opinion.

The final episode of the season is the most shocking and moving episode of the show that we've ever seen. The final few moments are something that I didn't see coming, and it's unknown how everything will pan out for everyone in Season 5.
