This story lacks a primary source of knowledge. The director is trying to tell you something he doesn't know well himself. As a son of immigrants from the USSR he is obviously interested in his roots but he doesn't bother to learn about them before speading the news. As a result you will see an imaginary community of Brighton Beach that exists only in director's mind.
You will see some popular actors in this movie but not exactly a good acting from them.
