Drupal sites are often blamed for being dull and ugly. I have myself nagged about the limited amount of great contributed themes there are available. Drupal sites can be made as beautiful as sites using any other CMS. drupal sites network features thousands of sites build on Drupal. Some of them are boring, yes, but there are many interesting and nicely done examples of how great a Drupal site can be.
