> I'm just asking. How does it change the overall view?
Because he's rating the score itself how it pertains to the project Goldsmith or Horner wrote their scores are, NOT the album itself. Say if this is was a score review for a compilation of Goldsmith's Star Trek paired with Rosenman's inferior Star Trek IV. It would be unfair just to average in Goldsmith's 5-star effort with Rosenman's 2-star. Or what if this was just a separate 5-star score like The Hunt For Red October, where album's sound quality and track selections are sorely lacking.
Christian like to rate different aspects of a scores composition and its presentation on album so it doesn't look like he's handicapping a single composition because it was poorly presented or paired with an inferior score.
That's why, despite all categories receiving a 3-Star rating, he kept them all separate so he doesn't have people accusing him of "Goldsmith's Walton score is SO and 5 star effort! It's unfair you scored it with Horner's TOTALLY 1-star "Rascals and Robbers" causing it to be degraded to 3 stars. Also, it's not Goldsmith's fault that for cheap TV sound quality so you shouldn't count off for that!! BLAH BLAH BLAH!"
