The Man From U.N.C.L.E. is based a 60's TV show, is directed by Guy Ritchie and stars the British Henry Cavill playing an American, the American Armie Hammer playing a Russian and the Swedish Alicia Vikander playing a Brit. I actually had a lot of fun with the James Bond movie that never was.
First off, U.N.CLE. is very cliched. Don't have any misconceptions that there are twists and turns and you won't see what's coming next. You will. That being said, a cliched movie can still be good. The defining rule is that if the film is executed well and has at least one entertaining aspect throughout it, it's not a failure. Fortunately, The Man From U.N.C.L.E. has really great humor throughout it's runtime. The two that deliver the humor the most happen to be Cavil and Hammer, not only demonstrating their comedic acting; but also proving how well these two work together. I must admit, I felt Armie Hammer's character was a bit wasted. Without spoiling anything, an extremely interesting backstory is set up with him and they never really do anything with it. He doesn't really have an arc to overcome in the film either(neither of them do now that I think about it).
Another stumble on the film's part is that it seems a bit dated. It's now secret that the way films are made has evolved over time. Generally, you can take a guess as to when a film was made through details such as the camerawork, lighting,etc. Now The Man From U.N.C.L.E does feel like the 60's for sure, but some of the concepts and such are pretty dated. Much like Top Gun with all of it's 80's feel, The Man From U.N.C.L.E feels very 60's. Maybe too 60's. If it was made in the 60's and put to the screen then, it would have gone down as a classic. But this is not 1965, this is 2015. Thus, the film looks like a digitally remastered version of a 60's film.
All in all, there really isn't all that much to say about this film. Bad guy has bomb. Rivals need to work together. Laughter! Explosions! Excitement! Really fun time at the movies!
