- Box Office Bomb: The fourth biggest confirmed loss in film history after Mortal Engines, Cutthroat Island and The Lone Ranger (2013), it lost DreamWorks Animation $125 million. When adjusted for inflation that's $174 million in 2020 dollars.
- 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).
- Creator Killer: Sinbad was the last strike in a series of three consecutive box office bombs and critical underperformers for screenwriter John Logan, after Star Trek: Nemesis and The Time Machine. While The Last Samurai and The Aviator were financial and critical successes, it still led to Logan having only one writing credit for Sweeney Todd until The New 10's (he rebounded with Rango).
- Executive Meddling: 9/11 happened when the production already started. You can imagine how making an animated movie with Arab main character was looking in that climate. This led to extensive distancing from the source material, which in turn certain critics panned for being In Name Only gimmick.
- Genre-Killer: The film's low financial success caused DreamWorks to abandon 2D animation completely (at least in films), 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. And in the background if it all, Titan A.E. flopped two years earlier, trying to win a duel with Treasure Planet and instead killing "independent" animation. These three events combined might be why this blend of animation was never attempted again until 15 years later with My Little Pony: The Movie (2017), which grossed $60 million worldwide against a $6.5 million budget. However, as mentioned above, all three movies have since achieved moderate "cult hit" status, suggesting there might be some other reason for their less-than-stellar financial performance.
