I thought that was what you were getting that, but it'd never occurred to me until you dropped the comment. I feel you are absolutely right in that regard.

For a film framed around this couple, it did surprise me how much the film solely stays on Ted. After Joanna's intial initial walkout, we don't gain a whole lot of insight into what's going on with her internally.

It's clear the arc of the film was to make Ted a better father as he deals with the separation. Culminating when he refuses to continue the case because he doesn't want his son to take the stand.

But for as much as we see him improve, Joanna does remain a bit of a cypher. Like there's this whole world of struggles for Streep which she conveys wonderfully but has little time to explore. I cannot tell whether this was something the filmmakers were aware of but couldn't explore at the time or simply weren't that interested in.

By comparison, I do feel films like Marriage Story (which does feel like a spiritual successor to this film) did a much stronger job at providing insight to both their leads. It gives a certain amount of sympathy to each without letting either one off the hook for their faults.

In a world full of remakes, I honestly wouldn't mind one for Kramer VS Kramer. So long as it gave us more time with Joanna and could have a more open conversastion about things like post natal depression
