Took my mom to see this. Language was a bit rough, and lots of racist comments, but this is a very good movie, even if you're not wild about Clint Eastwood. It's rated R, and definitely an adult movie.
The language was very rough, a lot of f bombs and like you said it did have a lot of racist comments, in fact the movie is based on Clint Eastwood's characters racist thinking. My husband and I saw it a couple of weeks ago. It was an excellent movie.
