It just strikes me as a terrible way to read. To continue the analogy, I could watch a movie in fast forward and still work out what was going on and what the notable scenes were ("gosh, they're chasing him through the sewers of Vienna!"). But I wouldn't have experienced the art of the film whatsoever. Reading faster is more difficult, but similarly unhelpful. I realized a long time ago that there was literally no point trying to speed up my reading pace, and nothing to be gained from speed reading. You need to give your imagination time to explore the detail and connotations of the descriptions, not merely the meaning of the words. Otherwise you're just as well reading the cliff-notes.
