One of the most interesting character relationships in the film is that of Butler and Thomason. She's a single mother just trying to support a young son with whom she's obviously very close, constantly Skyping with him and encouraging his efforts as a Little League Baseball player. She's also like a big sister — albeit a competitive one — to Butler, but she's all about their corporate mission, and at odds with him when his conscience begins to jeopardize their chances at landing those drilling rights for the $9 billion company for which they work, a firm that's just bestowed a big promotion on Butler.
Krasinski — who developed the original story idea — and Damon have written a solid script loaded with fully realized characters to whom any audience can relate. And the story's basic message — about a society that still allows open-minded debate over grave issues — is well worth considering.
