The character of Iris
I found Iris so unlikable that it diminished my interest in the story, even though I realize that part of the story is having her evolve from thinking only of herself to going to extreme lengths for a woman she just met on a train.
Here are two questions:
1) In the Hitchcock version, was Iris more likable? It's been years since I've seen it, but I don't remember her being so off-putting.
2) Is this version of Iris more true to the way she's depicted in "The Wheel Spins?"
