Steven Spielberg's Bridge of Spies is as square as a 1979 videogame character, corny enough to nearly be not just a period piece from 1957 but also a film from then, and its pretty dang decent. Tom Hanks in his most Jimmy Stewart-ish role yet, is a lawyer who gets inadvertently sucked into a incident in where he must first defend, and then negotiate a trade involving a captured Russian spy in America, and he's gonna do right for this man even though he's not a red-blooded American and works for the enemy because gosh darn its just the right thing to do.
Besides being a film your parents and grandparents have probably already seen and liked, its funnier then you'd expect, with some enjoyably tart dialog and recreations of idyllic 50's America (thanks Coen bros, who scripted here). Did I mention this film is square as heck, well, it is, but that don't mean its bad. Through the lens of a 50's Cold War drama it makes a number of salient points that are relevant to today (just like how Spielberg's pretty darn good Lincoln was quite obviously allegorical to a number of topical political issues). The political commentary is all subtext, but its there. If you want to see a well made film for adults, something that's not dark for the sake of darkness, something that doesn't condescend to the audience and is smarter and funnier then it appears to be, then this is a good choice.
