For all its faults, there is a kind of genius in the way that it takes the rom-com raison d'etre - the desire to see two lovable people fall in love with each other - and diverts it for its own purposes.
But, but, but: Mann and Diaz make a surprisingly entertaining comedy team, swiping at each other with impeccable timing... the whole enterprise is at least 40 percent better than you ever thought it could be.
Though Nine to Five played out as an ensemble film, The Other Woman is totally taken over by Mann, who swipes every scene with her hilariously sympathetic portrayal of a needy, ditzy, and slightly manic wife.
No one knows which takes are funny and which aren't. More than once, all three women, especially poor Upton, are caught looking like they don't know what they're doing.
One of those lame comedies that pretends allegiance to the female demographic but spends most of its time toiling around in sub-moronic, playground-level sexual politics.
