Hu Bo's An Elephant Sitting Still is a film steeped in philosophical contemplation, examining intense feelings of hopelessness through the experiences of four characters each grappling with difficult circumstances and longing for an exit from their suffering. Even though it runs close to four hours and unfolds at a deliberate pace, the movie presents a visceral and affecting story, supported by strong acting and a pervasive sense of sadness; however, some viewers might find the visuals and the unresolved conclusion disappointing. The sorrowful history surrounding the film's production—Hu Bo’s death by suicide after disagreements about his artistic vision—contributes another layer of grief to this already somber work.
