But he cannot say "Movie A is good" with genuine truth, without any sort of subjectivity or perspective. Because good isn't real. Maybe to you and me and him and font guy. But that doesn't make good real.
Sure, to some extent you can say that "good" is just a matter of subjective definition, but that would be a truism and you'd accomplish nothing by saying it.
While no person can say that a certain movie or game or whatever is "good" with some sense of Absolute Truth, what you CAN judge is whether it adheres to certain principles of good design or good art. Exactly what those principles should be is debatable. But if you were to take two steaks and say that you think Steak A is delicious and Steak B tastes lousy, then, yes, while to some extent that is just a matter of subjective taste, there is also a certain standard you're already judging the stakes by on a subconscious level. In your mind, there is a certain quality in the steak that you are looking for. It is a quality on which Steak A delivers beautifully, and Steak B falters. By analyzing the quality you look for in a steak, you can, to some extent, speak objectively about subjective taste.
And if you come to discuss the issue with other people and find that they too seek the same quality in a steak, then you can establish that as a sort of guideline by which to judge it. That doesn't mean that your guideline will be Absolutely True, but it serves as a useful point of comparison.
Honestly, there are different philosophies of criticism, but I won't really get into that. I do however think that it's good and constructive to have discussions over things being "good" or "bad", and the more we have of it, the better, as long as it's based on actual thought and reason rather than just rabid fanboyism. Just because there's no Absolute Truth about it, that doesn't mean we shouldn't discuss it and argue about it! We all have our own reasons for liking and disliking certain things, and understanding those reasons, those subjective and relatively random differences between people, is fascinating.
There's nothing more insipid or annoying than a person who kills an interesting argument by bleating "THAT'S JUST YOUR OPINION!"
