I think you just need to accept that Jackman factually is not the perfect Wolverine, whether you like him or not.
He's one adaptation of a character that existed long before him and an adaptation that strays from the original in ways that are absolutely NOT necessary and have nothing to do with suspension of belief. Just completely nothing. PLENTY of actors out there who fit Wolverine's physique better than Jackman. He didn't make Wolverine, he made a Wolverine.
Also concerning different audiences, we've never seen the Wolverine from the comics on screen, we've rarely seen any comic book character truly portrayed like in the comics on screen, for almost no characters. So you can't back that statement up with any proof.
If anything Marvel Studios' success proves you wrong, because although those aren't perfect copies brought to life either, most of them are closer to their original counterparts than Jackman is to Wolverine. Same for Spidey now, regardless of whether that new film is any good.
I think it's exactly the opposite, I think we'll learn as time progresses that much more people would like the actual proper versions of these characters than is often presumed. If you look at CB filmography and it's success versus it's progression, that certainly seems to be the case I'd say. The more films have directly taken the CB versions, the overall more success they started having. One can often mention Nolan to disprove that theory, but Batman Begins was quite an accurate CB year one Batman. It's TDK and TDKR that started watering that down, instead of increasing it.
Also, I never had much access to the comics as a kid, but the more I learn about the comics, the more I see why these characters were designed the way they were, or why writers took them in certain directions. Those reasons often heavily outweigh the reasons filmmakers make their versions the way they do, which often don't have much to do with the character itself at all.
And the current Wolverine is a good example of that.
