To say that “Country Strong” (2011) is a somewhat sad film is to say that Hank Williams sorta knew how to sing about loneliness. It should have been nominated for “feel bad movie of the year.” (Somehow, I can even hear a lonesome whistle blowing in the distance as I write this review.) Garrett Hedlund, Tim McGraw, Leighton Meester and Gwyneth Paltrow all give great performances, but their characters are as dysfunctional as a Nashville trailer park. They are awful hard to love. Good music, though. Hell, maybe that’s the point. Hank probably could have written a song about it.
