Right. RT score of 29% and cinema score of B says nothing about the movie. We are just projecting our personal preferences on the masses if we think it is bad.... Nevermind that the same can be said about those who think it is good. They too are projecting their personal preferences on the masses.
You're forgetting how much the mass audience's (including critics) appeal over dramas is quite poor.
"The Dark Knight" was a movie that, at its time of release, would not have made the same success without Heath's tragic demise, because it was essentially a crime drama featuring Batman, Joker and Two Face.
I remember leaving the theater kind of depressed by the movie, but I never would have dare call it a bad feature.
Now, go look up RT scores of all crime dramas released in a year.
They're always generally treated very poorly, because they don't have mass appeal.
For example, "Blitz" starring Jason Statham, a very dark movie which had a scene so violent I had to turn it off, stands at 6.2 on IMDb and 48% on RT with an average of 5.1/10 from critics and 36% with an average of 3/5 from audience.
Does it make the movie an objective disgrace?
No, I wouldn't dare judge it like that.
Technically, it's done very well, it's just not a family movie.
I might actually give it another chance when I'll be in the right mood to rewatch it.
To conclude, the market is now geared towards the Star Wars/Marvel packaging, but WB tried the same thing with Green Lantern and the audience responded badly, so how can you blame them for going the MoS/BvS route?
