“Air” (**1/2 out of four) was a pleasant if unexceptional melodrama set in the mid-1980’s in which a determined shoe salesman (Matt Damon) led the company of Nike in signing a then-unknown basketball player named Michael Jordan in a groundbreaking and blockbuster deal that would change the fortunes of the company and led to the explosion of lucrative sports endorsement deals in the landscape since. Sensational opening sequence plunges us right in the heart of the capitalistic decade of the Reagan ’80’s and holds you with its good cast and detail but gradually (no pun intended) the air comes out of the story and it loses its grip. Viola Davis is superb as usual as Jordan’s caring mom and Damon holds the movie together through its various lulls.
