It's also irritating that there's so little pretense that this is a real documentary. In This is Spinal Tap , a major part of the humor was derived from the absurdities of rock documentaries. Rob Reiner, who directed This is Spinal Tap , also appeared as the director of the supposed documentary, whose usual work in commercials have given him delusions of grandeur. Much of the humor there came from the interplay of Reiner and the members of Spinal Tap in the interviews. In Best in Show , on the other hand, we never see any of the interviewers asking the participants questions, and we get few of the hand-held camera shots that look like real documentary footage.
Most scenes are indistinguishable from a fictional film.
There's no explanation why the documentary happened to pick five participants who all take first in their categories at the show. Besides the gay couple played by Higgins and McKean, we learn that Coolidge and her dog trainer, played by Jane Lynch, are lesbian lovers. In Waiting for Guffman , Guest's character was a closeted but obvious homosexual, and it was implied that a character played by Michael Hitchcock had unacknowledged desires for him. If you object to it, it's Guest and Levey going out of the way to put homosexual characters in their films. If you don't, it's offensive that they think that all gay characters are funny.
