The very concept of a dragon is a beautiful legend, but all the obsessions with dragons, various cults, and shoving them into everything – that's complete nonsense (a waste of good art, in your opinion).
When a dragon fits the context, it's very effective, but when it doesn't... well, you get the idea. As for the artwork, there are about as many good pieces as there are for other themes.
