Part of the reason I'd never really watched It's a Wonderful Life is that my father does a very accurate Jimmy Stewart impression. He does it very often and very insistently. He has done this since I was very young. It was funny when I was a child, embarrassing when I was a tween, tiresome when I was a teenager, and by the time I had become an adult, it was background noise that I would really rather do without. Like Maroon 5.
This is all to say: I was over Mr. Stewart and his entire oeuvre before he ever had a chance.
