Here's what happens:
My parents are 60 years old. They loved the original ghostbusters. They couldn't even begin to tell you what "a reddit" is and probably not even what a forum is.
This is what they see when they open the NYT for the review:
Half of the reviews (edit: meaning ones you find on major sites and papers - not just the NYT ones) seemingly delve into gender wars bullshit about online voting and likes. Then the actual relevant part of the review commonly mentions that it is mediocre or decent. My parents flip to the next page of the paper. Completely turned off from the movie. They'll see something else, if not see no movie at all. I might get a call a few days later, if they remember, asking to explain what half the bs was about.
Just realize how many people could not give two shits about the gender wars bullshit connected to this movie. Think about the number of people who only saw two pieces of media concerning this movie: a subpar trailer and a review that drones on about internet drama. Wesley Morris from the NYT made an excellent point in how many of the reviews tried to tell people that seeing the movie in essence was making a political statement and how it just completely turned people off.
So, yes, the reaction to the reaction definitely harmed the movie.
