title: How to crawl IMDB? [Read more] button not being pressed
body: <p>I'm Extracting IMDB movie reviews.</p>
  
  <p>There is a problem
  To bring up the movie reviews,
  The [read-more] button must be pressed.</p>
  
  <p>But after the review is over,
  I don't know how to end this.</p>
  
  <p>It is currently being handled in a 'polling' way.
  How can you handle this more intelligently?</p>
  
  <p>when there is more to read:</p>
