It's not a website. It's an interactive Flash animation. And not a particularly good one, at that. It did manage to bring down Firefox, which is impressive--the build I'm using has been rock-solid so far.

By website, I mean a collection of information substantially based upon and made available by the standards promulgated by the World Wide Web Consortium, such as (X)HTML, CSS, and the Web Content Accessibility Guidelines. The substantive content of StarWars.com is not described by the W3C standards, it's in a proprietary media format embedded into the a web page. Going this route will cost them some users and hurt their search engine rankings, but it's their choice. I'm sure there's any number of CSS geeks who would be willing to design a standards-compliant, accessible website for them when they get tired of the Flash.
