Last spring left a lot of unanswered questions for fans of NBC's Thursday night lineup: Did Ross propose to Rachel? Did Grace get pregnant with Will's baby? Did Dr. Carter survive the smallpox outbreak? Did J.D. work out everyone's problems?

At first glance, the fourth question might not seem to fit in with the other three. But now that Scrubs has moved to the cozy NBC timeslot of 8:30 on Thursday nights, viewers will soon find themselves as anxious to follow the second season of the offbeat and unpredictable medical comedy as any other "must see TV" show.

Last year, Scrubs premiered on Tuesday nights to high critical acclaim but only moderate ratings. The first season detailed the life of medical intern J.D. (Zach Braff), and his daily life at the Sacred Heart Hospital. Through constant and hysterical use of inner monologue and fantasy sequences à la Ally McBeal, the viewer is in constant perspective of how J.D. views the wacky world around him.

The ensemble cast's chemistry is the most fluid and seamless since Cheers left the air. The show's writers have carefully carved exceptionally distinctive personalities for both the main and supporting roles.

J.D.'s best friend is Turk (Donald Faison), a wisecracking surgical resident in love with domineering nurse Carla (Judy Reyes). Sarah Chalke plays Elliot, J.D.'s neurotic and easily manipulated love interest.

The show's funniest and most exceptionally written character is the exceedingly witty and sarcastic Dr. Cox, played by the hilarious John C. McGinley. McGinley's character is the most three-dimensional role this reviewer has ever seen in a 30-minute sitcom. Although Dr. Cox comes off as a jerk at first, J.D. spends much of the first season learning the sad facts as to what has made him such a bitter soul.

What makes this show so fantastic is its well-placed use of drama. While Scrubs is categorically a comedy, it adds a touch of seriousness to each episode, unlike much of today's slapstick, nonsensical fare. Each character's conflicts are real and their emotions genuine. Fan of the prematurely cancelled Sports Night will assuredly appreciate the perfect blend of the two genres here.

Last season's finale left viewers hanging as Dr. Cox's ex-wife threw a monkey wrench into everyone's already complicated relationships by revealing secrets that each of them had been hiding from one another.

Leaving episodes worth of material to resolve for the next season, the writers had no idea that the show would move into one of television's most coveted time slots. The season-opener made it apparent that the writers quickly resolved most characters' relationships in order to clean the storyboard, as not to ostracize any new viewers.

As a fan, it was slightly disappointing to see the show take the easy road, but after seeing the opener finish an amazing ninth in the Nielsen ratings, the move obviously paid off.

With a fresh start, the show can only go up from here. What it comes down to is this: you know Ross and Rachel will get together, you know Dr. Carter will survive smallpox, but you never know what will happen next on Scrubs.
