Does a film being nominated for or winning an Academy Award (Oscar) affect whether or not you want to see it? Not really.
Have you ever watched a movie based solely on the fact that it was nominated for or won an Oscar? Nope.
How many of this year's nominees have you seen? 1 Which ones? Howl's Moving Castle
Do you think the film and/or actor deserved the nomination? YES
Are there any you wanted to see but have not managed to do so yet? Yes: Capote, Narnia, Harry Potter, War of the Worlds, King Kong, Good Night and Good Luck, Walk the Line, Munich, Charlie & the Chocolate Factory, Pride & Prejudice, The Corpse Bride, and Wallace & Grommit. No, we don't get out much. I will see them all eventually.

As far as a detailed commentary on the nominations, I'll leave it to Jeffrey Overstreet since I pretty much agree with him across the board.
