I’ve never seen more than a few minutes of the TV show, but the humor in this show is still accessible to people who have even just a passing familiarity with the characters and the concept.
What I didn't like
Like most previews, there are some transitions that could be tightened and smoothed, but the cast is so stellar that they frequently improvised into the technical gaffes and played them for additional laughs.
My overall impression
An entertaining skewering of the TV show, bolstered by excellent casting with stellar vocals.
