Ryan Gosling though. He's got emotion and charisma acting abilities somewhere between Keanu Reeves and a block of mahogany.
I don't think it's fair to say he lacks charisma by pointing to his performance in a movie where he plays a replicant living in a depressing dystopian world. If he had been all smiles and charisma I would have found it unbelievable.
I've actually met Ryan Gosling... and by "met" I mean I was in the same room as him while he interacted with other people. It was around 1999-2000 (during his "Young Hercules" years, I believe) and he came into the store I was working for at the time. Maybe something tragic happened to him since then that crushed his soul, but that kid had charisma. There was no doubt he'd be famous.
He probably wouldn't have been the first person I'd think of if I was casting the role of Neil Armstrong, but I don't think he is a bad choice.
