I kinda get what you mean. I think that the fact is she dissent look threatening (like Susan Boyle) people have taken to her. Although not a fan, Leona Lewis sings equally as boring music and does with (in some peoples eyes) stellar vocals and is struggling with album sales.
I still think that if Adele looked her age and was slimmer if would've been a different story, this is not to say that she's not talented but every middle aged woman across the world can relate to her.
