A romantic comedy that's about as romantic as Raging Bull and not nearly as funny, Lane Janger's Just One Time comes from the Eric Schaeffer (If Lucy Fell) school of independent filmmaking, in which a smarmy, narcissistic writer-director grossly overestimates his own charisma by casting himself in the lead role. Half-shaven and lethargic, with a self-pitying pout as his default expression, Janger comes across like a bush-league David Schwimmer, sporting a hangdog demeanor that wouldn't seem charming under the best of circumstances. But few actors could carry out the passive-aggressive torture sessions he has in store for appealing co-star Joelle Carter and still expect to win the audience's sympathy. With only a few weeks until his marriage to the lovely and successful Carter, New York City firefighter Janger sabotages their blissful engagement by bullying her into his long-held fantasy of a three-way with another woman. She's hurt by his request, but agrees to it under the condition that he make a similar sacrifice and participate in a three-way with another man. At that point, she's essentially called his bluff, and any sensible adult would realize how miserable a ménage à trois would be for all involved. But Janger inexplicably persists, leading them to seek out gay (Guillermo Díaz) and lesbian (Jennifer Esposito) partners for the occasion. Since neither of them really wants to go through with it, the end credits should have rolled after about 10 minutes, which is still much longer than a sane couple would have taken to arrive at the sane conclusion. But Janger drags the madness out for an eternity, guilting Carter into something she doesn't want to do, whining when she doesn't want to do it, and then flying into fits of jealousy at the thought of her falling for another woman. Apparently, this sadistic monster is Janger's idea of a charming romantic hero. When he's shown racing through the city streets like Woody Allen in Manhattan, Just One Time goes from unlikely to unseemly, a fitting end to a case study on miscalculation.
