Honestly, I liked it A LOT more than Frost/Nixon. I even liked it more than Slumdog Millionaire, which was a darling little film that I will be delighted to see win come Oscar night. Still, Doubt should've been up there, in the top five this year. And don't get me started about how it should've replaced the terrible The Curious Case of Benjamin Button.
