They tried to put too much silliness and poor placement of humor that wasn't necessary. You really didn't get to know the men involved and that made the movie choppy. It was a good story but could have been written and directed better.
Dame Judy Dench is one of the best living actresses ever. She demonstrated the human and soft side of this real-to-life woman and with the excellent writing, we see how great the movie is. Everyone should run to see this movie.
