This will probably work well in the TV series, and there's nothing wrong with it, but seems strangely out of place in the cinema. And instead of the opening crawl, we get a montage and voice-over in a 1930s serial style. After the strange feeling of seeing the 'Warner Bros' logo and hearing 'As Time Goes By' in place of the Fox logo and fanfare, the film gets off to an inauspicious start - a rendition of John Williams' Star Wars Main Theme played by The London Philharmonic's cheapest non-union Mexican equivalent. But even the venerable and generally even-handed Roger Ebert didn't have much good to say about it.
Although I say 'critical', it's always best to remember that angry nerds with broadband are not film critics. I went to see 'The Clone Wars' with carefully measured expectations, given the very, very mixed critical reaction.
