Ghostbusters 2016 - why is she licking a gun?

On March 3rd Sony and Columbia released the 1st trailer for the upcoming film, Ghostbusters. This new film is not being marketed as a sequel, but rather a reimagining/reboot of the franchise. It features 4 scientists in New York City who develop equipment to capture ghosts - much like the 1984 film of the same name. But the question remains is this a remake, reboot, sequel, or stand alone movie? The opening seconds of this trailer refer to the original movies - but yet the film supposedly doesn't acknowledge these events ever happened. I share my thoughts and comparisons between some of the scenes shown in the new trailer versus the original Ghostbusters Movie from 1984, and a bit added from the sequel, Ghostbusters 2 in 1989. Ghostbusters 2016 stars: Melissa McCarthy as Abby Yates Kate McKinnon as Jillian Holtzmann Kristen Wiig as Erin Gilbert Leslie Jones as Patty Tolan Chris Hemmsworth as Kevin Directed by Paul Feig Produced by Ivan Reitman Cameos from original cast include Dan Aykroyd, Bill Murray, Ernie Hudson, Sigourney Weaver, Annie Potts
