Barbara Streisand Miscast
Streisand ruined this movie for me. Her character was annoying but with a more charming actress like Audrey Hepburn or Natalie Wood I could've looked past it. I can maybe even see someone like Bette Davis playing this role back in the 1930s or 40s. To add to that I don't think she had much chemistry with Redford.
With that said I love the concept of the film and I wouldn't want to see it remade.
