# ===============================================
 
# initialize a url and feed into Nokogiri

doc = Nokogiri::HTML(open(url))

# Creates an array that contains all the rotten/fresh
# reviews on the page along with their respective critics

# drills down to the lowest level that still contains all necessary data
critics = doc.css('div#reviews div.quote_bubble')

reviews_array = []

  # drills down to pull out a critic's name
  name = critic.css('div.media_block_content div.bold')
  name = name.text.strip
  review = [name] # saves the name into an array called review

  # drills down to the element that may contain a fresh class
  fresh = critic.css('div.quote_contents div.fresh')
  
  #checks if a fresh class exists
  if fresh.empty?
    review << "rotten"
  else
    review << "fresh"
