"Grounds for Marriage" is watchable but I also found the plot to be silly and just hate the sort of singing that Kathryn Grayson did in this film. If you like very operatic music, perhaps you won't mind it like I did.
When the film begins, you learn that Linc (Van Johnson) and Ina (Grayson) have been divorced for a few years and Linc is now planning on remarrying. Inexplicably, Ina wants Linc back--though exactly why is never really explored. In fact, it seems as if she wanted the divorce in order to follow her dream career--and now she is scheming to get him back despite him upcoming marriage to another lady.
In order to get Linc's attention, she pretends to have a throat disorder and they call for a doctor--and Linc just happens to be that doctor. Now any sane doctor would have refused the case and referred her on to another--especially since she announced that she's trying to rekindle their dead marriage. But he doesn't--and eventually you know exactly how it's all going to end.
Aside from the singing, the worst part about the film was Grayson's character. At times she was shrill and late in the film when Linc wants her back(???), she runs off in a huff--and this makes zero sense in light of her working so hard to get him. Overall, she comes off as petulant and childish and you have no idea why Linc would want her.
At the very best, this is a silly time-waster--a film to watch when you don't want anything intellectually taxing.
