The travails of our four main characters continues as J.D. (Braff), Turk (Faison), Elliott (Chalke) and Carla (Reyes) continue to move up the medical ladder and their lives and careers continue to blossom, but not without a series of missteps and hijinks along the way.
Of course there is always the incessant sarcasm provided by Dr. Cox (John C. McGinley) and Dr. Kelso (Ken Jenkins), which really is the true comedy of the show whereas the antics of the lead cast is reserved to either romantic comedy or slapstick humor, all of which blend well together to create a balanced attack.
Season four begins with J.D. and Elliott suffering through their recent break-up all while competing for the role as Chief Resident, a position the two eventually end up sharing creating a variety of comedic opportunities in an of itself. Carla and Turk are married and their relationship is challenged on a daily basis, but this is where the show shines as it rarely enters the realm of all out drama, which is something shows like "Friends" and "Will & Grace" were unable to do successfully. "Scrubs" remains a comedy-first show, which allows for the laughs to continue as the emotional drama of the show is able to work itself slowly into the plotline.
Season four's greatest asset is the choice in guest stars and there are several to delight the audience and they aren't as distracting as guest stars are on most shows as they either have extended stays or serve there purpose and aren't greeted with the canned audience laugh and applause tracks that become increasingly annoying, that is except for the "My Life in Four Cameras" episode in which the creators actually spoof a sitcom and Clay Aiken is the "celebrity" to receive the audience applause.
Aside from Aiken other guest stars of note include Heather Graham, Richard Kind, Julianna Margulies, Matthew Perry, Michael Boatman, Molly Shannon and even Collin Farrell offers up a great turn as a wild Irishman.
On top of the show itself somehow the folks over at Disney continue to supply special features even for a fourth season sitcom, which most oftentimes are reserved to just the episodes themselves. A series of featurettes, an alternate lines feature, deleted scenes and two commentaries, one by Zach Braff on his first directed episode of "Scrubs," "My Last Chance" and another by Sarah Chalke on previously mentioned "My Life in Four Cameras."
On a whole this is another great addition to the "Scrubs" library and the show continues to be the funniest sitcom left on television. Once this show ends up leaving network television we are going to be in a serious bit of trouble as we are left to such blunders as "My Name is Earl" and "Two and a Half Men." What a couple of piles... "So's your face!"
