'A Real Pain' is a brilliant film that explores complex family dynamics and the impact of the past. Cousins David and Benji travel to Poland to honor their late grandmother, a Holocaust victim, and join a Jewish heritage tour. Director Jesse Eisenberg's handling of the Holocaust theme is masterful, balancing humor and sorrow with finesse. The film centers on the bond between David and Benji, contrasting their contrasting lives and personalities. Kieran Culkin gives an outstanding performance as Benji, and the film is a thought-provoking and authentic exploration of roots and the importance of understanding and support.
