Where there is passion, there is a greater multitude of connection. A creative work for example that is passionately put together shows a creator who is passionate about and interested in the subject and everything that subject connects to, and is largely possessed by it, and who sees at a higher fidelity of connection and at higher and greater scales, and faithfully transmits this vision to the work and represents this sweeping, connected vision in the work. And people tend to instinctively like this sort of thing, even if they don't fully comprehend or absorb it. Popular enduring works tend to bear this signature.
Lackluster and mediocre works on the other hand often display a knee-jerk adherence to waning conventions and the recycling of stale and decaying tropes. The life is literally draining from the work, both as a piece and as a socio-economic phenomenon. Exposed to it, one instinctually feels boxed in, dim, and dead.
