There are smart Hulks in the comic lore. And grey Hulks.

And all kinds of other Hulks.

But "The Hulk" - the myth - is rather about a Jekyll/Hyde/Frankenstein story of a man who gets angry and turns into an unstoppable green smashing machine. And it's true - the Hulk cannot be stopped. His power is that his anger/rage/pain/fear makes him stronger, thus, the more powerfully you were to beat on the Hulk, well, he'd only get stronger still. This of course plays to powerful, instinctual emotions in people. The feeling of power/powerlessness. Anger and the wish to smash your enemies, or everything. Freedom from constraints of society and morality. Fear of the monster lurking inside. Fear of power. Etc.

Super heroes from the comics - Superman, Batman, Hulk, etc, are our new myths, and they're all pretty awesome. Let Spidey be your guide, man. Or even Aquaman, if that's your thing. Swamp Thing says Amen!
