After almost a year of waiting, we finally have episodes 21 through 25 of this 40 episode series, bringing the total number available on DVD to 35 ... maybe we'll see the other five episodes some day. <Sigh!>
This disk does not have quite as many features as the other disks in the series (multiple languages, for example), but they did go back to the studio and enhance the music and audio effects, and the full-length commentary track provides insights into the making of the series.
Even though the target audience was adolescents, I'm in my 50s, and have been anxiously awaiting this "missing week" to complete my collection. (I pre-ordered it as soon as it was available, as I did with the other disks in the series.) As different from the movie as the movie was from the book, it is still Very Entertaining, and I really enjoy watching the reactions of people who see it for the first time. :-)
As revealed on one of the other disks, the actors recorded the scripts of two additional episodes, but they were never animated ... budget constraints near the end led to the creation of two "clip shows" to deliver the promised 40 episodes (5 episodes a week for 8 weeks.) We now have 7 of what should be 8 DVDs, and if enough fans buy them, maybe the producers will complete the unfinshed episodes and include them on a final DVD.
Cast your vote for completing the collection by buying this disk ... and if you haven't purchased any of the others yet, get this one first, because it's a well constructed, self-contained story arc that stands OK by itself, even if it is out-of-context.
