This is a great series, EXCEPT, like many others have stated, for the annoying Velma/Shaggy romance nonsense. Velma is a loner who does the thinking. Scooby and Shaggy are the best buddies who wont let ANYBODY, whether it's Velma or Angelina Jolie, get in between them.
They need to get back to the basics...the show's romantic elements make it look like Degrassi High or B.H. 90210. Keep the romance out of it and get back to the basics....a bunch of friends, try to solve mysteries, two of which (Scooby and Shaggy) always end up facing the adventure together, with plenty of good food, and scary monsters to keep them busy.
The series HAS featured these elements, but the romance has gotten in the way. Take the romantic nonsense out of it (Besides, Daphne is MY woman) and the show would be one of if not THE best Scooby Doo series' in history, right up there, with "What's New, Scooby Doo?".
I also agree: Release the ENTIRE Season, instead of this "four episodes here, four episodes there", junk, which is done to make the "Volume price" of $9.99 more attractive to the buyer than the "Season price" which would be about $25 to $30. Think about the fans of the show, instead of profits for a change.
