Sequels or remakes of films that have marked the history of cinema or that have been a generational symbol of a given period are unlikely for me to be successful because the manufacturer's desire to resurrect a brand solely for profit is evident. often leaving out the emotional part that binds people to these films.
I watched Ghostbusters Legacy a little with different eyes, after reading the positive reviews, and I inevitably got carried away to the first film of the series, as there are some brief references to the 1984 film in the plot. The protagonists of the film are Egon's grandchildren Spengler (the late Harold Ramis), who came to his home as heirs, together with Egon's mother and daughter, after his disappearance to defend the city of Summerville from ghosts. Her niece Phoebe discovers that the city and the mine were built by the architect Ivo Shandor (the load-bearing structure of the New York building, the epicenter of the events that occurred in the film Ghostbusters - Ghostbusters, was built by the mad architect himself with selenium taken from the mine).
Hence Phoebe's investigation to discover the secrets of the mine, the ghosts, the discovery of grandfather Egon's equipment and the final showdown with Gozer!
The film is really well built, there are many references to the 1984 film and nostalgics like me have certainly enjoyed it (the mini version of the marshmallow puppet is really nice). Seeing the Ecto-1 traveling on the road again was really exciting but the scene with the greatest pathos is certainly the ending: Egon's ghost appears next to his niece Phoebe and, with the help of real ghostbusters and friends Peter, Ray and Winston, inevitably aged, they defeat Gozer once again, saving the city of Summerville and the entire world.
Another element of continuity is the direction, entrusted to Jason Reitman, son of the late Ivan, director of the first two films. A continuity much appreciated by the fans and above all did not disappoint expectations. Adorable.
