Doing some more research for the site and I can across Scooby-Doo! Mystery Incorporated. A new series made last year. The animation is great and is funny as hell without being to disrespectful to the original show.

This show unlike previous reincarnations of the Scooby Doo seems to have an ungoing storylike from episode to episode..
