Jessica Chastain's bravura, committed performance lifts Michael Showalter's 'The Eyes of Tammy Faye' above its middling, problematic writing. While the makeup and costumes are stunning, and the performances are flawless, the plot isn't compelling enough to warrant a two-plus-hour run duration. It's still entertaining, but it blows the opportunity to provide incisive views on religion, politics, and money.
