One can be too precious about anything: sports, politics, dogs. It's best to stay away from that mode of worship. Here's a good example: famed grunge granddaddies, the Pixies. A few years ago they decided to get back together, and this time not just tour, but make some new songs. Well, you can imagine the dour reaction from the self-proclaimed Pixies cognoscenti when not only did the music not sound like their heroin-soaked output of yesteryear, but (GASP) featured a bass player NOT named "Kim Deal".
