There are some very funny moments and lots of cool stuff in this movie, that in my view just about tip the balance in favour of coughing up ten quid to see it. The opening sequence, a car chase through the grimy streets of East Berlin in Trabants, is just a delight, very witty and actually quite thrilling.
The rest of the movie doesn't quite measure up to this - its plot (secret society of Nazis want to develop their own atom bombs and take over the world; Alicia Vikander is recruited to get at her rocket scientist father) is a bit thin, very much a case of style over substance, but what the hey? It ain't Shakespeare, and I don't recall that the original 60s TV series was one of great depth and political insight either. The tragic flaws of the movie are really its two leads - if you could get over the fundamental improbability of two such ridiculously good-looking blokes being spies, you would soon be chuckling away at their splendid wooden-ness.
Henry Cavill, to paraphrase the wonderfully modest Robert Taylor (speaking about himself), is a good-looking kid, but can't act his way out of a paper bag. In addition, he clearly has spent so many hours in the gym bulking himself up to Superman size, that he looks just plain silly in a suit; 1960s suits were not designed for chaps with giant bulging muscles but for rather unfit chaps who smoked and drank a lot, rather like Dan Draper in Mad Men.
Armie Hammer, in addition to being quite supernaturally tall, is very very slightly less block-like than Henry Cavill, but I'm sorry - I know comparisons are odious and all that, but he just isn't in the same ball park for exuding brooding sexual tension as David McCallum, the original Ilya Kuryakin, currently to be seen as Ducky in NCIS. The biggest faux pas was to cast the wondrous Alicia Vikander as the heroine, because she really can act, and steals every scene she is in. Bottom line - looks fabulous, is great fun, see once.
