Despite being directed by Francis Ford Coppola, "You're a Big Boy Now" has pretty much been forgotten in the fifty years that have passed since it first played in theaters. After watching it, I think I have a grasp on a possible answer for why it's drifted into obscurity. I'm not saying it's a bad movie. The movie does capture the era quite well; those wanting to learn about styles and other period details will find the movie handy. Also, Coppola directs the movie with great energy throughout, from bizarre camera angles to offbeat performances.
But while the movie is directed with gusto, it doesn't manage to mask a big problem with the movie. The first half of the movie is really slow going with the story. Sure, the direction hides this thin story for a while, but eventually you realize that not much of substance is actually happening. Things do start moving after the halfway point or so, but it's kind of hard to get involved with what's happening because none of the characters are really all that sympathetic. Even the hero fails to arouse sympathy, because he is for the most part a real spineless wimp. The fact that all the performers give really broad performances doesn't help. In the end, the movie can only be recommended to people with real special interest in Hollywood filmmaking from this period, and even they might find it tough going at times.
