by Ian Pugh Knight and Day, Salt, and The Tourist failed as '60s spy throwbacks because they constantly reassured you that everything would be all right; if there was something about their various intrigues we didn't quite understand (or weren't supposed to know before some big third-act twist), we could rest assured that someone was pulling the strings to keep the world from falling apart. Unknown finally removes that safety net, and from there it approaches the fear and uncertainty that so fascinated Alfred Hitchcock and Terence Young about the Cold War--this sinking feeling that whatever conspiracies may be driving the plot, there will never be a way to extricate yourself from their tangled webs. True, Unknown's primary attraction is the dissection of identity, and it's simply incapable of stunning you in the same way that the Bourne trilogy stunned you with its own methodical examinations of the self. (If the picture feels derivative of that series, that's because it is.) But at the end, you're left feeling uncomfortable, because you just know you haven't uncovered all its secrets yet.
