If I didn't know better I would say this is an infomercial for all Jewish mothers who are really concerned that their sons marry nice Jewish girls, have Jewish kids....well you get the idea.
Although this film is promoted for its sophisticated storyline, Meryl Streep adds the only charisma and sophistication to the entire film. Streep definitely outshines Uma Thurman and Bryan Greenberg in this film. In fact, she is the only person carrying it. Her acting is superb as always, and she delivers her lines with impeccable timing and emotion. Thurman and Greenberg, on the other hand, appear like two awkward teenagers throughout the film. They had zero chemistry, and Greenberg's acting fed nothing to Thurman for her to work off of. Greenburg, despite his dashing, cute puppy looks, could not carry the leading man role because he seemed afraid to take the reigns. But Thurman wasn't better off anyway; it seemed like she was trying to take hold of her role throughout the entire film but she just couldn't get it right for some reason. Maybe the concept of the film was just too hard for her to work with, or maybe the script itself just gave her very little to begin with. Nonetheless, Rafi and Dave's dialog is trite, cliché, and very middle school at times. Everything they said to each other seemed expected of them and didn't add any new insights to their intellect, emotional maturity, or the maturity of the relationship. You could never really understand why the two were together besides the excitement from the age difference and the sexual exploration. Their romance unfolds in the most obvious and least charming fashion. The dates they go on seem unrealistic for a 37-year-old divorcée. (i.e. Underground rap clubs.) All of the romance that is supposed to touch you and bring you closer to the characters really just pushes you away because the scenes seemed force.
And you can't help but notice that their relationship is based on a large part on sex, which doesn't add any dimension to the characters or the story. Perhaps this is why it is so hard to swallow anything when both Rafi and Dave claim that they love each other. Because you can't help but think that they're merely infatuated with each other and this new experience and that it's not really love at all. Despite the fact that Rafi insists to her therapist/Dave's mom that she is serious about this relationship, it is hard to believe because you see nothing that Rafi and Dave have in common besides art and even that link is iffy and seems tacked on just to draw some connection between them. Younger never gives the characters real dimension or qualities that would make the audience draw towards them, so when the film ends, you don't feel the connection with the characters that is needed for the ending to be felt the way Younger wants it to be felt.
"Prime" is interesting enough to ask the right questions about age and relationships and the outcome of the decisions made. It also provides reasonable plot expectation for the audience and adds some twists here and there to surpass their expectation which concludes to a decent romantic-comedy.
