Similarly, positivity is presented as a uniquely powerful force. Their previous combined efforts defeated Gozer, a god of destruction, but the Ghostbusters are completely powerless against Vigo and the accumulated negativity fuelling him. It is only when the citizens gathered outside the museum unite to sing a chorus of "Auld Lang Syne" that their positivity overwhelms Vigo, allowing the Ghostbusters to defeat him. In 2016, A. Bowdoin van Riper wrote that while destruction-heavy films set in New York made before the September 11 terrorist attack had taken on darker, unintended meanings, "GhostbustersII" was now more relevant. Its ending, which can be seen as "hokey" or false, now seemed "touchingly real". Murray described it as a "story about innocence restored, and good values, and the power of faith in ordinary people." Unlike "Ghostbusters", "GhostbustersII" lauds the values of community and family over their Ghostbusters' personal successes. Indeed, the Ghostbusters' involvement in the sequel comes from the threat to their personal acquaintance Dana Barrett and her son. They are drawn out of retirement and break the rules of their legal settlement with the city to help, despite the lack of financial rewards and the personal risk to themselves.
