It is a simalr thing that I have seen in some of the Disney's live action movies. While Will Smith wasn't bad he was no Robin Williams. The same goes with Magnificent Seven. There is a reason that people still love Steve McQueen movies decades later. So while actors like Denzel Washington did a decent job they just could not bring about that on screen magic in the same way.
I think that's the big issue, actually. When they made Aladdin, Williams was working in a vaccum, when they made the live action one Smith was working in a world where everyone would be comparing his performance to William's. That's a frankly unfair standard for most actors to meet (unless you're Karl Urban in Dredd, then you casually out-act Stallone and his whole face with just your jaw).
I think it's worse the closer together the two works are, because the first guy gets to be the character, the second guy feels like they're trying to be the first guy.
