As a general rule I don't like James Stewart, I know I know, I'm sorry. But I don't. I don't like It's a Wonderful Life. I find his speech patterns annoying, and I've never found him to be particularly attractive.
I just watched The Shop Around the Corner (aka, the movie that later became You've Got Mail) and now I have a bit of a crush on Jimmy. He was so endearing and charming. And I could see why so many people like him.
So thank-you Shop Around the Corner for changing my mind about Mr. Stewart.
