I am of the belief that Christopher Guest is a genius, and "This is Spinal Tap" is probably the best example of that. It's full of quotables-all I've got to do is look at my significant other and say, "He's the patron saint of quality footwear" or, "We're not going to do f-ing Stonehenge!" and we collapse in hysteria. Rob Reiner also made a lot of good movies after his days of playing the Meathead were over, and I've always missed him in other Guest productions. Also,the music in this film is actually pretty good; if you don't listen too closely to the lyrics and ignore the titles, you might almost think you were listening to a bona fide band! This was the first of the genre for Guest, although I'm willing to bet "A Mighty Wind" will probably be the last. Although still very, very funny, it had kind of lost it's "quirky" appeal by that time.
