This animated film was directed by Don Bluth (All Dogs Go To Heaven) and the writers included Joss Whedon (Buffy) and Ben Edlund (The Tick), but it's more problematic than that sounds: at times it's trying desperately to be a kid's movie, and at others it wants to be a serious movie that merely happens to be animated. The film suffers from Development Hell: the plot and characters sometimes change out of nowhere, seams where older drafts were glued together to make the final script. The soundtrack is also rather badly mismatched. But despite the problems, it's the most adult-targeted film Don Bluth has ever done, and it's enjoyable: it has a generally legit and intelligent story, the setting is great, the visuals are great, and it trends toward relatively hard sci-fi. I liked it. Score: 3 stars out of 4.
