"This Is Spinal Tap" Review

Last night before bed, I was looking for a decent movie to watch with a relatively short run time.  I got what I was looking for in Rob Reiner's 82-minute rock & roll send-up, This Is Spinal Tap.
Reiner plays film documentarian Marty DiBergi, who is on the road with fictional British rock band Spinal Tap on their North American tour.  DiBergi hopes to document the inner creative workings of "Britain's loudest band" and showcase them to the world through this film, as explained in prologue.
It should be noted that This is Spinal Tap is a "mockumentary", which is essentially a documentary style film with a fictional subject matter or fictional characters.  This style has been utilized by television shows such as NBC's The Office, and for this reason Spinal Tap plays out in a manner very similar to the popular Thursday-night comedy.  I think the format works here for the movie because, like The Office, the audience gets funny interviews with the characters as they comment on events transpiring in their lives.  I also enjoy the humor in seeing Rob Reiner, the actual director of This is Spinal Tap acting in the picture as a fictional filmmaker.
The script is hilarious, and it's cool to pick out some of the influence the writers borrowed from real-life rock bands.  I also enjoyed seeing Spinal Tap evolve and undergo creative transformations throughout the course of the film.  My favorite part is when guitarist Nigel Tufnel (played by Christopher Guest) shows DiBergi (Rob Reiner) his collection of "axes" and other equipment, including an amplifier whose volume goes all the way to 11.  1 louder than the usual 10.  It's a classic scene that I recognize from years of playing the family's favorite board game, "Scene It?".

Check this one out on Netflix for a good chuckle.  3 of 4 stars.
