“The Mule” is the latest Clint Eastwood directed movie. He also stars in it, acting for the first time since “Gran Torino”. The film is better than his films lately. This time he plays a horticulturalist who is so into his flowers that he neglects his family. Late in life he earns money as a driver for the drug cartel The pace of the film is better than most of his movies and it keeps moving. Not his best, but not bad.
