I can’t tell you how many times, even in notable magazines, I’ve read movie reviews that spoil the movie. It’s the most criminal, careless thing a critic can do: steal the narrative potency of someone else’s work. Even if it’s the worst movie in the world, a decent critic can tear it apart without spoiling the film.
So the other day on netflix I saw this – a spoiler warning:

On every review any user can flag reviews for spoilers.

Thank you Netflix.
[...] scottberkun.com » What every movie review website needsMy only qualm is that I think people might not even know to look there. My instinct is that people have been trained to think of a “Flag This” button being limited to inappropriate content, rather than for something like spoilers. [...]
Well, our reviews are all spoiler-free!
Fuck spoilers! Why bother reading a review anyway?
I’ve written 200 Movie Reviews for a book. Until I removed them, they were by far the very best on the internet.
I AM THE NUMBER ONE SPOILER! That’s my job as a Movie Reviewer.
For example, Eddie Murphy’s PLUTO NASH has a surprise villain. NOBODY on the internet mentioned who it is. I MENTIONED THAT EDDIE MURPHY PLAYS THE VILLAIN and I mentioned it in the first sentence of my review!
Repeat: If you don’t want so-called Spoilers, don’t read fucking Movie Reviews.
We try not to write spoilers, but occasionally they slip. Nothing big, but especially when writing about classic films, it’s hard not to mention things that are assumed to be common knowledge.
I noticed spoiler warnings in Wikipedia movie articles as well.
The spoiler reviews are not always bad, sometimes they can save you from hours of torture.
