The big DVD news in the Star Wars universe is the release of season four of the animated Clone Wars.
At first, this series was largely viewed by purists as 'something for kids, cashing in'. Like the movies themselves were ever not for children...
It can hardly be called 'cashing in', when it's Lucasfilm producing the cartoon adventures. That makes it canon and therefore a solid addition to the movie storylines.
Moreover, the quality of production, and the darkness of some plot devices, soon won over even the most elitist of fans. This is no side story. It's the reality of what led to the rise of the Galactic Empire; and it set the scene for the transformation of Anakin Skywalker.
What happens in Clone Wars really does come to fruition in the legendary Star Wars films, hence they are very worthy prequels. Even if they are animated.
No Star Wars fan needs an introduction to the concept of the Clone Wars, as it underpins the later stories. But it's worth running through what the animated series is all about.
As the name would suggest, it chronicles the terrible reality of an inter-galactic war. It's within living memory of many older Star Wars characters, hence some familiar names are in the various battles. Season four, for example, introduced a very young Darth Maul.
Personally, I think it's worth checking out, even if you've disdained it until now.
