I've never seen the first one. I guess now is a good time to watch it.
I've always heard it referenced, and that it is a good movie. I don't know why I've never seen it.
Not a good movie... way, way better than that!
Definitely see it.
That said, you sort of have to be a 'classic Rock' fan and an early X-er or a later Boomer to 'get it.' The references to the entire Rock and Roll community and to the trend for "Rockumentaries" (Stop Making Sense, The Last Waltz, Gimme Shelter, The Song Remains The Same, Tommy, The Kids Are Alright, Floyd at Pompeii, Woodstock) all did 'band profiles.' So you sort of have to understand the "Rockumentary" culture to really get everything out of Spinal Tap.
They lampoon everyone, too. Zepplin, The Beatles, the Stones, Jethro Tull, early Metallica and metal, The Who... everyone who was great back then! Definitely download/rent/stream/buy DVD...
By way of tribute to the movie... when I bought my first ever DVD player in 1998 or so... the first movie I bought was "This is Spinal Tap." The second was Saving Private Ryan.
I will definitely be re-watching the original before seeing the sequal.

PS. Also going to see Happy Gilmore II. The original was awesome! And the reviews are great!
