You're right the Wolverine character/behavior is pretty much spot on in the movie in relation to the comic, but in this case, you can't judge the Aquaman character yet because we have no idea what they're doing with him in the DCMU. And as far as the Wolverine look, yes, there was a complete departure from the comic...he's a foot taller and doesn't wear yellow spandex and a ridiculous mask. The only thing that was the same was the claws. You can make a case for the way they did his hair up to look similar to the mask, but I don't think it counts. So I think my comparison is very valid if we're just judging by appearance alone, which is what your reaction to Aquaman seems like.
