Proves Leighton Meester can act
No matter how the film does, Country Strong will probably be remembered as Leighton Meester's break-out film. Simply put, she proved that she can act (and _sing_ for that matter, but above all, act). Leighton had a _very different_ role in this movie from Gossip Girl or her other upcoming movie, the Roommate, _stepped into the role_ and nailed it.
Not to diss GG or The Roommate, but Meester's performance as the "damaged but still smiling smalltown prom queen" Chiles Stanton could put her in the league of other younger actresses now destined to have long careers in Hollywood like Amy Adams and Anne Hathaway.
