Not sure I can pick. Especially, It's a Wonderful Life. Jimmy Stewart is just so perfect along with the rest of the cast.
Laney, you do have a good point on how things have changed and that would be interesting to see it remade for that reason. When you think about George Bailey wanting to jump a bridge over $8000.00 seems laughable today because that is not that much money in this day and time. A modern version would be interesting and I would watch it but I don't think it could ever replace the way I feel about the original.
I will have to think on it and get back to it later.
