This is such a SOLID 3 stars. I loved the look of it, the soundtrack and the cast. Kristen Stewart gives a full, vivid, nuanced performance and Vaughn, unencumbered by any audience expectation of "goodness", delivers a blisteringly unrestrained nastiness and steals every scene he's in.
Every department is peaked and ready for something special. The script just can't seem to figure out what everyone else in the cast and crew has made sense of - what this intersection of political harassment, stardom and activism has that's fresh and exciting to offer two hours of storytelling.
