The Man from U.N.C.L.E. is, of course, a quite recent movie, but I think it qualifies as overlooked because not many people saw it. Did you?
The movie is based on the TV series that is by now remembered mainly by folks of the geezer persuasion (that would be me). I really liked the first season of the show, but I thought it went downhill a bit after that. It was hard to beat the combo of the suave cool of Napoleon Solo (Robert Vaughan) and the hot young sex symbol (yes, really) Illya Kuryakin (David McCallum). The movie can't really capture the vibe that the TV series had back in the old days.
Solo (Henry Cavill) and Kuryakin (Armie Hammer) didn't have a backstory on the TV series, so naturally we have to have yet another origin story movie. Solo, it seems was a great thief, and to avoid prison after being caught he has to work for the CIA. Kuryakin is a Russian agent and near superman with a bad temper. They're forced to work together by their bosses to avert (of course) the destruction of the world by nasty Nazi remnants in the Cold War world. They're helped (and hindered) by Alicia Virkander, who wears the Carnaby Street look very well, indeed. Mr. Waverley is played by Hugh Grant, who's very good.
There's a lot of action, a bit of wit, and some gorgeous color, but Cavill and Hammer aren't going to make anybody forget Vaughan and McCallum. The plot is the same old, same old. The movie was directed by Guy Ritchie, which is enough to turn some people off from the start.
Not me, though. I found it entertaining and frequently amusing. If the sequel they set up at the end ever gets made (highly doubtful), I'd watch.
