An anonymous reader shares an excerpt from a report via CNET: Our increasing obsession with trailers is changing how we watch movies. We're becoming audiences afraid of surprise, audiences that would rather watch movies we're certain we'll like than risk watching films that surprise us into love. In some cases, this fixation is even lowering the quality of movies themselves by encouraging bad filmmaking habits. The most extreme example happened when Warner Bros. released such a successful trailer for 'Suicide Squad' it brought on the company that cut it to edit the whole film -- dropping the director's original cut altogether. [...] Thanks to trailers' easy accessibility on YouTube and those shot-by-shot breakdowns that quickly appear online once trailers drop, anyone interested in a given flick can pore over all the available footage for hours -- even if that leads to major spoilers for them and everyone they share it with.
