You've never met anyone on film quite like Benji, so brilliantly played here by Kieran Culkin. At first he seems like a standard movie type, the annoying and selfish but charming and lovable guy, as he both bullies and inspires his sensible cousin David (Jesse Eisenberg) on their tour of Poland. Everything Benji does is funny but as the movie goes on, everything he does becomes fascinating and sad at the same time. This bittersweet, sharply drawn comedy character is your way into a deeply thoughtful but somehow also light and limber film about present-day Jews' relationship with the Holocaust.
