“Pure Country, Pure Heart” (**1/2 out of four) was a sincerely done third entry in the “Pure County” series about two young sisters (Kaitlyn Bausch and Cozi Zuellsdorff) who go to Nashville upon finding out that their late father was a country music singer. Predictable at every turn but carried along by the solid chemistry between the two girls and a lot of colorful Nashville scenery. George Strait sits this entry out but Willie Nelson at an ageless 84 years old makes a good musical appearance at the very end. Shawn Michaels and Ronny Cox are solid also in key supporting roles.
