I loved the movie but hot goddamn was the marketing bad for it. When your marketing is literally based around alienating not just the old fans but any potential new ones by blanketing criticism for the movie as "misogyny", and specifically targeting AVGN for his refusal to review it even though his opinion was no more invalid than Polygon's, and specifically attacking not just him but his f***ing wife and daughter? I'm sure that turned a lot of people off.
That says nothing of the fact that... Why wasn't this merchandised more? I'm an early millenial, I was born in '87, so I remember the toy craze of the early 90's, so I specifically remember having tons of Ghostbusters toys and merch, and because I watch Cartoon Network for Teen Titans Go and Steven Universe (and that's it), I don't recall EVER seeing an add for a new proton pack toy, toy weapons, merch aimed at young girls and boys, none of that. Why?
My only response to people saying Sony marketing wasn't responsible for the shitty reception the trailers got is this video:
http://redlettermedia.com/scientist-man-analyzes-ghostbusters-2016/
It's a comedic video, and it uses generalizations of MRA's and TUMBLRina's opinions and I take some parts of it with a grain of salt, but it made me better understand some of the backlash for other issues mounted against the movie.
So with attack pieces, audience alienation, manufacturered controversy, no merchandising, what the capital F*** did they think was going to happen? Because I don't buy the excuse that "women-led movies don't sell". It's always gone back to "BAD SHITBIRD women-led movies don't sell". Make a good one, or even a decent one (Hunger Games series, Divergent series), and it'll sell.
