I've seen this movie numerous times, and found it to be an interesting part of the Digimon storyline. However, not every part of this movie was worth writing home about. While the first two segments expanded on plots mentioned in the TV show, the third movie was one big void. No episode since then has mentioned the events of that segment, and it's the only part of the movie that we don't know when it takes place. We know the first part takes place 4 years prior to Season 1, and the events of this segment are shown in flashbacks during the episode "Return to Highton View Terrace." We also know that the second part of the film takes place shortly after Season 1, although the events after the last episode of Season 1 have not been clarified, so we don't have an exact point of reference. Finally, the third part seems to have just been thrown in to show the Season 2 cast, pre-Ken's conversion to the good side.
Now that I've finished that part, I'd like to say that the second segment, called "Our War Game" in Japan, was my favorite part. Even if the concept was a bit hokey (It's Digimon, the whole concept is hokey if you think about it.), it still was written extremely well. It also answered the question we've all been asking: "When will someone attack them while they're Digivolving?" All in all, I rate the segments of this film as follows: Favorite: Segment 2 "Our War Game", followed by Segment 1 (can't remember the title in Japan), and then Segment 3 (also can't remember the title!).
