My family just saw this and absolutely loved it within the first 10 minutes. First, I loved the awkwardness of the granddaughter and how it’s similar to the mother when she tries to flirt. And the feeling of nostalgia at almost every turn, from the same soundtrack to seeing the van. I even loved how they kept the ‘cheesy’ CGI with the gatekeeper and key master. And the ending just made me cry. Seeing all the original ghostbusters and then the ghost of the grandfather. Then the end “for Harold” I loved it. In my opinion there’s no need for a sequel or any more more movies. To me, this is the perfect ending.
