title: Do not match if word appears in regex
body: <p>I have a url, and I want it to NOT match if the word 'season' is contained in the url. Here are two examples:</p>
  
  <pre><code>CONTAINS SEASON, DO NOT MATCH
  'http://imdb.com/title/tt0285331/episodes?this=1&amp;season=7&amp;ref_=tt_eps_sn_7'
  
  DOES NOT CONTAIN SEASON, MATCH
  'http://imdb.com/title/tt0285331/
  </code></pre>
  
  <p>Here is what I have so far, but I'm afraid the <code>.+</code> will match everything until the end. What would be the correct regex to use here?</p>
  
  <pre><code>r'http://imdb.com/title/tt(\d)+/.+^[season].+'
  </code></pre>
