From dialogue so hokey it could be printed on a tea towel to mind-numbing storylines – how can a glossy take on John Grisham’s novel about a fiery law graduate be so tedious?

The Rainmaker was once merely an average film about lawyers starring Matt Damon. Now, thanks to the magic of television, it’s a below-average series about lawyers starring a man who looks like Matt Damon. This is one Milo Callaghan, whose jawline suggests a certain mettle, but whose acting suggests much woe. Or at least a fitful unease with the role in which he finds himself. Accordingly, he drifts around this 10-part John Grisham adaptation with the air of a man who has forgotten what he came into the courtroom for, certain only that whatever it was, it was not a drama that compels him to say things like: “Ah just wanna be a lawyer.”

Callaghan plays Rudy Baylor, an ambitious South Carolina law graduate with a social conscience and a thirst for justice. Rudy wants to make a difference but dammit if his fiery temper don’t keep conspirin’ to screw up his plans. The huffing greenhorn is even late for his first day at prestigious law firm Tinley Britt, having spent the morning hurling his mom’s lunkish boyfriend around the garden (“You think ah’m gonna let you keep leechin’ off ma mother? Gnyaaarrr!”).
