The original was so ground breaking. My mom saw it in the theater and made her hesitate about marriage. She also said it helped make Liv Ullmann more known in America.
It also inspired Knots Landing, Family, and other family dramas on TV in the 70s and early 80s.
I do think a remake is cool because marriage in the 21st century has different challenges (technology, higher cost of living, more muddled gender lines). But my fear is that it would be bias and favor the wife over the husband...when in the original version..both were flawed and equally at fault for their marital issues.
