Deanna Durbin made many movies, mostly bad. But the ones that are good make all the others palatable, including "Lady on a train". She was a unique personality. Almost impossible not to like. For example, It's like watching John Wayne walk through one boring, formulaic plot after another and not minding because you just like John Wayne. So to be thoroughly charmed by Deanna Durbin, you have to inoculate yourself against the dumb plots she was given later in her career. First dose should be with one of the best stories. "It started with eve" That should win you over for anything to come later. Then it's good to go to the beginning, her first picture, "Three Smart Girls" when she was a little girl and won everyone's hearts ( but be warned the story and direction are bit creaky). Your third dose should be "Three smart girls grow up" by this time your ready to take on and enjoy any of her movies regardless of plot. I do admit to fast-forwarding past some of her singing in her later movies, but that's because they're badly placed in the story and tend to slow things down to a crawl. Bottom line, she's something special and not to be missed.
