Why does The Dark Tower's running time terrify Stephen King fans?

People have been clamouring for Idris Elba to finally get a major movie all to himself for years, but his big summer blockbuster vehicle, the first in a proposed franchise of adaptations of Stephen King‘s seven-book long The Dark Tower series, is already garnering negative buzz — something punctuated by the news that the film will be just 95 minutes long.

According to an update on the official BBFC website, the film, which opens in a month, rejects the traditionally bloated running times of recent blockbusters and clocks in at a lean hour and a half. But the news has sparked concern in fans of the original novels, who have already grown worried about the numerous changes made to the story.
