The point I'm making is, there IS NO "REAL" SCORE at all, and to pretend there is means there's some misconception somewhere (or a load of naivete).
As for the rest... yeah, financial decisions rule one particular kind of "success", that's for sure. Sublime masterpieces aren't going to lead to much if they don't also generate revenue. A big problem in science-fiction especially, since it's often quite expensive to make those visions come to life; whereas some random novel about a Bohemian living in an attic in Paris could probably be made for $10,000 >_>
