I like Clint Eastwood. I like most Clint Eastwood movies. "Gran Torino" is no exception.
Basically, the story involves recently widowed Walt who lives in a changing neighborhood. Walt likes to growl and complain. Estranged from his own family, he unwillingly gets involved with the Hmong family next door. There is gang violence involved, and Walt decides he has to do something about it.
Like most Clint Eastwood movies, it is best not to examine this one too closely, or you will notice that there is only one multi-dimensional character and that the rest of the cast is there to move the plot along. And don't think too much about how good-natured the Hmong are about being called a wide variety of racial epithets. And don't get caught up in wondering if your own death will have meaning.
Instead, laugh out loud when Walt decides to "man up" his teenage neighbor Thao by teaching him how men talk to each other (it involves a lot of profanity and ethnic slurs) and cry a little about the need for some to drag down the others and nod approvingly at the surprisingly satisfying ending.
