I don't know, they may have a point. I mean since RotJ, what exactly has been better for the franchise than Snips? Jar Jar? The prequels? Endless tides of mostly mediocre novels? Some pretty good video games? Mara Jade?
I suppose a better, more accurate assertion would be that the Clone Wars show as a whole is the best thing that's happened to Star Wars in 20 years.
