Christian Bale is very much unlike Batman, but he's still hailed as one of the best. In all reality, Jackman did the best he could and pulled it off well. He's naturally a skinny dude, so there's no way he could have managed to build his weight up to match the comic book Wolverine. And as for unattractive... well he's only meant to be 'ugly' because that's his character. In all reality, Jackman's face very much suits Wolverine when he's grown his facial hair.

The problem I have with Jackman's Wolverine isn't his fault; it's the writers. Wolverine isn't meant to be a weary rebel with a heart of gold, at least not how I've grown to know him. He's meant to be a violent sociopath that's frankly distrusted by the X-Men and always feels like he's one step away from straight up murdering everyone there. Apart from that he's incredibly intelligent and somehow manages to pull off stealth when needed, despite his size and reputation. Jackman's Wolverine... is too clean, in terms of personality. He's too relaxed, choosing brooding over ass kicking. He needs to do something gory once in a while, to remind people how, deep down, he's an animal, as his name suggests.
