Creator Backlash: Zigzagged with animator Kevin Koch. On his Synchro Lux blog, he made it clear that while he enjoyed working on the film, he thought it was the least favorite animated film he helped make, taking it to task for its story flaws (too much focus on a vaguely explained MacGuffin that kicks off the whole plot and unwittingly deflates the films tension by raising the stakes to a level that makes it impossible to suspend your disbelief) and claiming the lead characters were boring and unengaging (pointing out that Sinbad is basically the biggest asshole in the universe for wanting to steal a book that would send the whole world spiraling into chaos in the wrong hands).
Genre-Killer: The film's low financial success caused Dreamworks to abandon 2D animation completely, turning to CGI movies such as Shrek. Interestingly, the 2002 Treasure Planet did the exact same thing to Disney, causing them to leave traditional animation for the Computer-generated variety. These two events combined might be why this blend of animation has never been seen since. However, as mentioned above, both movies have since achieved moderate "cult hit" status, suggesting there might be some other reason for their less-than-stellar financial performance.
