Disclaimer: i've used Drupal for a couple of projects and I like it for its easyness for noncoder, this is just about the cons: Drupal is very good and powerful (i think the best part is the ability to create custom contents with CCK - now included in core in D7), surely more "CMS" than WP, but it's far from being perfect. As someone wrote in another comment, sometimes it's a nightmare (theming or just finding the right module and hoping it wont give you problems with other modules). There are also people saying it has become more and more overbloated http://www.unleashedmind.com/en/blog/sun/the-drupal-crisis others stating that it's better to move to more developing oriented framework: http://erickennedy.org/Drupal-7-Reasons-to-Switch and big consulting company that has worked with Drupal and is now moving to other: http://drupalradar.com/breaking-development-seed-quits-drupa...

I think every single CMS/platform/framework can be criticized or even demonized if you search well.
