Can there possibly be an easier target for a savage satirical comedy than sexually disgraced megachurch televangelists? Lee-Curtis and Trinitie Childs, the embattled Baptist power couple played by Sterling K. Brown and Regina Hall in "Honk for Jesus. Save Your Soul." can barely compete with Jim and Tammy Faye Bakker for cartoony excess. If anything, "Honk for Jesus" feels almost too real to qualify as satire.
