If the story is unsatisfactory, it wasn't told correctly.
I'm still sure that some scenarios can't be adequately told, but anyway, that's well off-topic.

The Monomyth applies to almost all storytelling, because that's all heroic myths were, stories, told by people.
I think that's overestimating the monomyth's scope, although after considering it, I'll admit that the monomyth does apply to more than just the ancient heroic myths. But I'm certain it is too reliant on one style of mythic storytelling. It still has some huge limitations regarding its relevance to modern society. The monomyth is still heavily geared towards males, for instance, and the supernatural focus has been mostly lost nowadays. There are still parts that match Campbell's theory, whether obvious elements or requiring interpretation, but he had quite a lot of broad classification for narrative elements so that's hardly surprising.
The modern developments of the theory could well have eliminated those issues though. It's still a very popular theory in screen-writing apparently, but it's meant to have contributed to the prevalence of rigid three act narratives.
I really need to read that damn book. I always end having conversations about it and have to get by on what I remember from a lecture, its wikipedia page and a section in a Star Wars documentary.
EDIT: Just had a look at Christopher Vogler's take on mythic structure and his simpler account of the stages actually look pretty convincing, when accepted in a broad sense. Dammit, I don't like changing my mind.
