With a name like Prime, a movie had better be about something more than an older woman digging on a younger man, much to the disapproval of the younger man's mom. It ought to be about, oh, I dunno, math or something--like Pi or Proof or even Primer, Shane Carruth's dizzying debut of 2004, in which two guys figure out how to travel a few hours into the past to make a little extra cash. Or maybe it could tell the story of Alan Greenspan and his race against time to lower the prime rate before a meteor collides with Earth, or perhaps it might be the story of a slab of prime rib that comes to life to attack unaware diners, or could be there's even a tale to be told of TV executives forced at gunpoint to program prime-time with an endless loop of According to Jim. The possibilities, though admittedly a bit on the awful side (surely, a studio exec could do much better, right?), are endless; but all you're going to wind up with is, yes, an older woman digging on a younger man, much to the disapproval of the younger man's mom, which adds up to zero, which, alas, is not a prime number at all.
Just what the title has to do with the movie is of some mystery, one that might be unlocked by those who pay close attention to the movie (and if you are one of those people, you really should see more movies). Perhaps it has something to do with the fact Rafi Gardet (Uma Thurman), whose name sounds like something you might order with a side of hummus, is an "older woman" in her sexual prime--older being her late 30s, and only studio executives would classify this as being older. (No wonder Shirley MacLaine was relegated to the final half of the Cameron Diaz-Toni Collette sisterhood pic In Her Shoes; in movie-studio years, MacLaine's been dead since 1997.)
This would explain why Rafi, just divorced from a man apparently her own age and possessing the libido of a corpse, winds up with a much younger man named David Bloomberg (Bryan Greenberg)--much younger being his early 20s, though Greenberg and Thurman look all of nine months apart. Rafi needs a young man to satisfy her needs. Men her own age apparently don't have the stamina to fuck her all night on every surface in her apartment, which is an issue writer-director Ben Younger, already a creaky 31, might need to take up with his therapist or a trainer or a stack of self-help books.
Or perhaps the Prime in the title is intended to signify the twosome Rafi and David become against her better judgment and his mother's wishes, his mother being played by Meryl Streep as though she's auditioning for a summer-stock production of Fiddler on the Roof. See, two is a prime number. So, there's that. David and Rafi have more than their age difference acting as a barrier between newfound lust and long-lasting love; their religions, too, are working against then. He's Jewish, she's not, which ain't kosher with David's mom, Lisa, who's either seen noshing on giant corned beef sandwiches on her apartment rooftop or sitting at the Sabbath dinner table on Friday night, alongside her husband and parents, with whom David also lives. This movie's so Jewish that come the year 2018, it'll have to get bar mitzvahed.
But there is one complication even bigger than the age and religious differences: Lisa is also Rafi's therapist, a fact Younger blessedly doesn't keep concealed from the audience for too long. Lisa figures this out long before Rafi or David, however, which makes her not only a lousy, conniving mom, but also perhaps the most unethical therapist in New York City. Lisa's guilt-ridden over the deception, of course, but not enough to stop Rafi from describing the beauty of David's penis during their myriad sessions that devolve into sex chat. Younger, maker of the overheated Boiler Room some years back (notable as one of the few movies ever to put Vin Diesel in a tie), throws more roadblocks in front of his lovers than a state trooper.
But the problem with the discrepancies in their age is a cheat; theirs is a June-July romance, at best. Younger might have earned his tension by casting an older actress, but Thurman, at 35, has the mien and temperament (and wardrobe) of someone far younger; and Greenberg, playing a painter of intimate, wide-screen portraitures, carries himself as someone far older. And Lisa's less a concerned mother than a pain in the ass; the woman loses all sympathy, and credibility, the moment she betrays her son and patient, yet still Prime demands we think her caring and loving. Younger, for whatever reason, simply can't abide their happiness, and so he destructs the relationship from time to time for no reason, using plot devices that wouldn't have been out of place in episodes of Three's Company. (One involves David's slacker-schmuck pal Morris, played by Boiler Room's Jon Abrahams, hiding in a closet, which angers Rafi . . . why?) His is just more conventional schmaltz, served up on a paper plate.
