There's a great little sleeper on DVD today (7/14). It's called Dakota Skye and it's much more complex and heartfelt than your typical indie/Sundance fare.
Dakota is cursed with the super power of being able to tell when anyone is lying to her. In this little coming-of-age indie film, her increasingly disillusioned world is turned upside down by the arrival in town of a stranger who always seems to tell the truth.
