Doris Day's Love Faucet - Spoilers
I really enjoyed this movie, but found the ending a little over the top where Doris Day's character (Martha), can turn her love on and off from one man to another so quickly like a water faucet within a couple of minutes.
So essentially she is pining for her man (Gary Mitchell character) for many, many months, writing him letters constantly while mentally/emotionally obsessed with him, and then telling Jack Carson's character (Doug Blake) that there is nothing like that between them, and showing zero romantic interest in him.
Then in the ending scene when she hooks up with Gary and sees what a cad he is, I can understand her not wanting to be with him. But in a matter of a few moments to suddenly fall romantically and deeply in love with Doug? I don't think the emotions of women act that way.
