Randomly choose an item from your Netflix Instant queue. Run it on the My List page (after loading the whole page).

(function(){
  var hd = document.querySelector('.main-header');
  var movies = [].slice.call(document.querySelectorAll('.slider-item'));
  var len = movies.length;
  var i = Math.floor(Math.random() * len) + 1;
  var movie = movies[i-1];
  movies.forEach(function(movie) { movie.style.border = 'none'; });
  movie.style.border = '2px solid red';
  console.log(movie.querySelector('[aria-label]').getAttribute('aria-label'));
  window.scrollBy(0, movie.getBoundingClientRect().top - hd.offsetHeight - 10);
