Usually, a major movie's first big trailer generates one of two reactions—passionate enthusiasm or shrugging indifference. That's certainly not the case with the new Ghostbusters film. Some, including myself, might see it as a movie that promises a mix of highs (Kristin Wiig and Kate McKinnon in perfectly cast roles) and lows (derivative gags and the only black character being a cringeworthy trope of sass and street smarts). But such middle-of-the-road perspectives are in short supply today. Instead, the reboot's trailer, released Thursday morning, has immediately become one of the most polarizing in recent memory. For some, it's yet another battleground in today's culture war over gender equality, feminism and the supposed marginalization of the American male. But it's also creating a generational divide, with quite a few children of the '80s feeling like their entire childhood is somehow riding on the quality of this film.
