Why not? Cats need a vacation too. What are you, pro-dog?

What would be awesome is if they filmed the special effects and scenes for the "original" comic series ending, and spliced them back in as a promotional gimmick to sell more DVDs. A version with seamless music to provide the "original" ending would make fanboys happy and give collectors a reason to buy it. And I'd love to see the effects they would have come up with - given Snyder's faithful recreation of the key comic book panels in various "signature" scenes, the NYC scene just before Manhattan and Silk Spectre pop in would be outstanding.
