Oh, goy! It's not news anymore that prejudice is bad and that anyone can be its victim. So, even though Focus is trying to get a clear view on anti-Semitism's insidiousness, one has to laugh when William H. Macy is taken for Jewish just because he has new glasses. That he should assume the same of Laura Dern solely based on her looks is obviously meant as some sort of object lesson, but the point gets beaten to death once the two marry, only to find themselves increasingly isolated by their neighbors.
Watching all of this is a real Jew (a broad David Paymer), who warns Macy not to underestimate people's ability to hate. Under Neal Slavin's laborious direction, the plot moves so predictably you can see the flat ending a mile away.
