The Mule movie's best attribute

Clint Eastwood's "The Mule" is based on a story of a 90 year old horticulturalist who ends up becoming a driver of drugs for the Mexican cartel, and the DEA agents who are looking to make busts against the cartel. Since he is an unlikely suspect due to his age, Eastwood's character flies under he radar of their detection. The best part of the film is Eastwood's bizarre and quirky interactions with a variety of people in the film. His character is older and out of touch and his interactions with different races, people of different sexualities, and other groups of society are so unusual and funny, because at his advanced age, Earl (Eastwood's character), doesn't hold back what he's thinking. When a character comments on that, he responds that he didn't know if he ever did.
