Half a century previously seemed an eternity to me. Let's just say it's not as impressive as it used to be. Bond may join Sherlock Holmes in the Immortality Club.
It's all relative! When I was a kid in the '60s, I thought the Universal horror films of the 1930s were positively prehistoric (but I loved 'em and still do). It blows my mind to think that the Bond films are now fifty-years-old. But, hey, none of us are getting any younger.
