Don't get this criticism:
As with so much that is said on IMDB, the criticism, understanding, and thoughts about this film seem limited to those in the fourth grade.
One of the most prominent descriptions (at times it is a criticism) is that it is "dated," and shows relationships between men and women as very old fashioned almost misogynistic. (there's a whole different problem). Fonda's character is confused about sex: "Should she, or shouldn't she?" "With whom" "When," Should she play the "nice girl," or "the vamp."?
These are all mindlessly simplistic views.
First, are there any other women in the film? Hellooooooooooo? Robertson hot red-headed number was doing gyrations, on and off planes, flying here and there, just to get laid. Was there something SHE was confused about? Her room mate? How about the hot blonde in the office Robertson flirts with? No, none of them belong to the category of woman that Fonda's did. But Fonda's character is the one the movie's about! So because of that we label an entire society as suffering the same way. Nonsense.
I came of age, so to speak, in the early seventies, and sadly, having never married, I have done a LOT of dating, and if you think women are less screwed up or less confused NOW and more "empowered," NOW than they were THEN, you're WAY off!
And you know what? You could go back another 40 years or so and find the SAME exact things true then. Just keep watching TCM long enough and you'll find it.
People don't change. One of the reasons these films are so appealing is because we identify with the characters, more or less.
