Arguments about "spoilers" are [SPOILER ALERT!] tedious and annoying, and nobody who feels strongly about such things one way or the other will ever convince the
fanatics people on the other side to agree with them, so such arguments are a huge waste of time and energy, and I have vowed [SPOILER ALERT!] to stay out of them for ever and ever and evermore, but now the film scholar David Bordwell has gone and made a fascinating blog post about [SPOILER ALERT!] how spoiler standards have changed and shifted over time and in various circumstances. Very much worth reading.
