I love this series and have been patiently awaiting a release on DVD; however, I was shocked when I finally received it and found it wasn't the complete series. It's not even numbered volume 1 or anything. It was only by reading reviews that I realized that this is the first of a possible three volume series and Shout Factory isn't planning on releasing the other two volumes unless they get good sales from this first one. Bah. Way to drive away the customers, Shout Factory!
The series deserves a five-star rating, hands down. Shout Factory's stinginess on releasing the whole series may kill their sales and thus provoke them to not release the other two volumes. Hard-core fans might have to stick to downloading the rare, low-quality, grainy episodes to get their "Adventures of Sonic the Hedgehog" fix. So overall rating: three stars. Release the rest of the series, Shout Factory!
