Speaking of movies that double as obvious socio-political commentary... I love V for Vendetta. It's fun and clever, and has some fantastic lines of dialogue. The Wachowski's are kind of known for fun, clever movies with memorable lines of dialogue. But I will say it's nowhere near as well-acted as the King's Speech though. V was a great symbol, but there's a limit to the range an actor - even one as iconic as Hugo Weaving - can portray with a mask on the whole time. I mean, Stephen Fry is brilliant in his minor role, but Natalie Portman is...well, she's not bad but I've just never been terribly in love with anything she's done. She's always the "oh yeah, she's in this movie too" actress. Whether it be to Hugo, Chris Hemsworth, Dustin Hoffman, etc., in my mind she's always been over-shadowed by a better performance.
King's Speech is a fantastic movie that turned a plot so simple - to the point where I didn't think I'd even enjoy it - and executed it so well it captivated me from beginning to end. And I mean it when I say it was better acted than V. I will fight to the death for Helena Bonham Carter and Geoffrey Rush. Colin Firth even held his own. I'm a bit sad to see this one leaning towards a win for V. Nothing against it, it's just not the better film in my opinion.
