As I said both in response to your other comment and in my original post, the plot *is* different. And I'm glad of that, because I didn't like the original story (which I read right after seeing the movie) nearly as well. On the other hand, it's also incorrect to say that it has "nothing" to do with the Padgett story.
The more you insist that it is connected to the original story, the harder it is for me to appreciate it on its own merits, or even to allow grudgingly that it might have some on which to be appreciated.
As for not liking the original story…de gustibus and all that, I guess.
Are you familiar with the term "McGuffin?" (Not sure if that's how to spell it, though). It describes the relationship between the two (such as it is) pretty well; they use the same McGuffin. The other resemblances are more of motifs than anything else, and I can't get into them without spewing spoilers.
