As Susan Sontag said , to understand art we shouldn’t focus on the content (whether that’s political art that tells us what we want to hear, or easy art that appeals to our genre preferences). Instead, we must be able to say how it is what it is . We must have read, seen, and heard enough to know how each new work compares, where it fits.

Good taste is accumulated through wide knowledge.

The more you sample, the better and broader your taste will be. The more you stick to what already speaks to you, the more limited and narrow your taste.
