Actually, I quite like Hanks. He is always watcheable and in the right part he is superb. However , because his name sells films he is in a lot of makeweight stuff, and it seems like this may be one of them.
The depth of the talent pool doesn’t change, but the way it is used and marketed does. Actors always get pigeonholed, it’s the nature of the game. Robert Downey Junior is always cast as a Tony Stark type hero character these days, but no one seems to remember his excellent portrayal of Chaplin. Another example is Tom Cruise. He is the epitome of the pretty boy action hero, but his performance as Ron Kovic in born on the Fourth of July was one of the great screen performances. It was the same with the old guard. Jimmy Stewart only ever really played Jimmy Stewart in all his films, as did John Wayne. However, Stewart, in Mr Smith goes to Washington, and Wayne, in True grit, show their true acting ability is far beyond the typecasting used in their marketing.
