That's ugly, but probably not a surprise.
So we have that, which is pretty much where every discussion I've seen of reviews and Ghostbusters comes to a screeching halt, online. There is much more though.Walk Hickey said:?Ghostbusters,? a revival of the 1984 original, hits theaters nationwide on Friday. As a reboot of a beloved, male-led science fiction film from the 1980s with a female-led cast, the reboot has proved somewhat controversial in the circles you would expect. But regardless of the quality of the film, it serves as a perfect demonstration of why internet movie ratings are inherently a problem.
Most fundamentally, single-number aggregations ? like those used by sites such as Rotten Tomatoes, Metacritic and IMDb ? are a pitiful way of explaining the diverse views of critics. More specifically, a vocal portion of men on the internet ? shall we say ? go out of their way to make their voices heard when it comes to judging entertainment aimed at women, and that appears to be happening with the new ?Ghostbusters.?
Hickey said:But let?s back up. Last year, as part of an investigation into the inflated ratings on Fandango?s website, I looked at the world of online movie ratings in general. The moral of this story: Each site that aggregates ratings and reviews has its own skew one way or another, and it?s up to the user to determine which heuristic most accurately matches what they?d consider an ideal rating. (Also, don?t trust always-positive movie reviews from sites trying to use that review to sell you movie tickets. That, too.)

That's ugly, but probably not a surprise.
Hickey said:Earlier this year, I also looked at IMDb?s user rating skew for television shows. Essentially, male users were more likely to rate television shows with a female-heavy audience lower than female users would rate male-centric television lower. Men were tanking the ratings of shows aimed at women.

Now we get to the bottom line:Hickey said:But this ?Ghostbusters? thing? It lays bare so, so much of what we?re investigating when it comes to the provenance and reliability of internet ratings.1 Namely, they?re inconsistent, easily manipulated and probably not worth half the stock we put in them.2 Here are a few stats I collected early Thursday for the new ?Ghostbusters? movie:
IMDb average user rating: 4.1 out of 10, of 12,921 reviewers
IMDb average user rating among men: 3.6 out of 10, of 7,547 reviewers
IMDb average user rating among women: 7.7 out of 10, of 1,564 reviewers
The movie isn?t even out in theaters as I?m writing this, but over 12,000 people have made their judgment. Male reviewers outnumber female reviewers nearly 5 to 1 and rate ?Ghostbusters? 4 points lower, on average.
But it?s not just IMDb, there are serious disagreements on ?Ghostbusters? across the whole universe of ratings aggregation sites:
Metacritic score of 61 out of 100, based on 41 critics.
Of the reviews aggregated by Metacritic, 24 were positive, 16 were mixed, 1 was negative.
Tomatometer score of 74 percent ?fresh? based on 138 reviews.
Of those reviews, the average rating was 6.5 out of 10.
Looking only at top critics, it had a Tomatometer score of 54 percent ?fresh? based on 35 reviews.
Of top reviewers, average rating was 6.3 out of 10.
This case demonstrates one way that ratings can be skewed, but in the context of how terribly skewed they already are. Does anyone here actually use review scores to determine what they buy though? I use trusted people who have similar taste to mine, so it's not an issue of broad recommendations. With Youtube... who doesn't do that?Hickey said:So even though 74 percent of critics enjoyed the film, according to Rotten Tomatoes, ?Ghostbusters? has an average score of 6.5 out of 10, so reviewers clearly didn?t love the film. A similar issue, only in the opposite direction, is apparent in the site?s top critics score. ?Top critics? is a somewhat exclusive category on Rotten Tomatoes, encompassing prolific and experienced critics at top publications with high circulations. Contrary to the hoi polloi of the Tomatometer, about half of reviews of ?Ghostbusters? from ?top critics? were negative, but it earned a middling-but-positive 6.3 out of 10, on average.3
...
, like the vast majority of people on earth, have not yet seen the new ?Ghostbusters? film. And to be honest, I don?t have a lot of skin in the game ? based on my birth date alone, ?Pokemon Go? is a bit more in line with manipulating my nostalgia for money than busting ghosts is.
The point is that this is a hugely instructive case for why internet ratings need to be approached with way more nuance than they currently are.4 People put far too much faith in numbers that are preliminary, decontextualized and, in the end, oversimplified.
