My one major complaint was the Winston Churchill actor. I mean how hard could it have been to get a good Churchill? He's not seen or heard much, though, so it's a minor quibble. But still...
Slate opens with this: "The King's Speech is an extremely well-made film with a seductive human interest plot, very prettily calculated to appeal to the smarter filmgoer and the latent Anglophile. But it perpetrates a gross falsification of history".
The NYT has a mixed review. Rolling Stone gives it 3 1/2 out of 4 stars and calls it "a crowning achievement powered by a dream cast". The Guardian describes it as "a richly enjoyable drama".
Roger Ebert gives it a full 4 stars. Rotten Tomatoes has a 95% critics rating.
