You just cited movies as an example of who is the more legendary/well known comic book character.
Some of us here still value COMICS, and the stories therein. As a comic book character, Hulk is the second most recognizeable in Marvels stable...and therefore should be treated like gold in all his representations.
If you disagree with that, then you must SURELY believe that Blade is further up on the Marvel hierarchy than say, almost every single character in their comic universe. Instead, Blade remains an almost unrecognizeable comic book character.
Regardless of their quality, Hulk has had a steady stream of merch and tv shows/movies for longer than Wolverine has even existed. Heck, Wolverine was a popular comic character for many years before the general public had ever heard of him, making his Q rating at the time awfully pathetic.
Hulk is more well known, therefore he is higher up in importance or in some "trinity". Marvel has dropped the ball again and again with the character, hurting his public image, but the fact remains that more people can identify Hulk in a picture than have ever heard of the character Wolverine.
