This movie was produced, directed, and stars Clint Eastwood. I personally like all his movies so I go in this with some bias. I think judging by the previews, this movie turns out much differently than you would expect. I know it was surprising for me.
The plot is straight forward and Eastwood really plays his character extremely well. I think as his character develops in the story, you start to like the character more. He is very unlikable in the beginning. His constant disapproving grunting made me laugh.
Anyways, I think if you like most of his movies, this one won't disappoint. If you don't like most of his movies, then I think this one will win you over.
Netflix:
Curmudgeonly Korean War veteran Walt Kowalski (Clint Eastwood, who also directs) must confront his Hmong immigrant neighbors -- and his own long-held prejudices -- when the family's teenage son, Thao (Bee Vang), tries to steal Walt's beloved 1972 Gran Torino. Walt soon assumes the unlikely role of guardian angel to young Thao and his sister Sue (Ahney Her), both of whom are vulnerable to local gang influences.
