Okay, some might say this is more of a chick flick than the kind of movie to suggest for your brother-in-law to enjoy, but if you like period dramas about the English monarchy (and doesn't everyone?), then this movie is for you. It was my second time seeing it and I'm already hankering to watch it again.
The cinematography is great, the costumes are sumptuous, the scenery is gorgeous, and the acting is excellent; I've enjoyed Emily Blunt's performances in other films (eg The Devil Wears Prada) previously, and this one certainly didn't disappoint.
And the music! There's a grand and glorious bit of Handel's Zadok The Priest; this was the moment at which Nathan decided the film was definitely worth watching.
[He's partial to that piece of music, perhaps in part because of the quite loud mention of "Nathan the prophet!"]
And if you are perhaps of the persuasion that mustaches on men are nice for fathers and grandfathers but not what you might call, well, "sexy," Rupert Friend as Prince Albert will probably change your mind on that point.
In short, you should probably watch this movie.
[It's available on Netflix for instant viewing.]
