This is based on my assumptions.
Initially, I was expecting to be a longer series but not a 6 piece. If you take a look, Both DA and DA02 had 50+ episodes while this is halved.
My biggest issue is that, they rather limit to a 6 piece movie so everything will rush itself at first, and then bait you with a possible installment due to the open end, it's very unorganized.
Imagine if being an actual continuation from the open end, it would likely be worse as everything was thrown out into the first 6 already.
Perhaps if Toei had given the series much more time instead of just 6 movies at once, the characters and story would have been way better given proper pacing. [The worse is that, this was an anniversary project, it feels like they're betraying fans expectation with this as a result to milk this to my opinion]
Onto the review!
Story: 6
Yeah honestly the story went downhill (messy too) since and to my opinion after the 3rd movie. A lot of things like the character build ups were neglected, I would say maybe it's because of the pacing? There's only so much you can fill with 6 movies while bringing out too many things. Things will be skipped. 6 for the story because it's still watchable as long as you're not focusing on details.
Art: 7
Not much different, the evolution is obviously the same since the first movie. Regarding the still images people were mentioning, I feel like they're just trying to emphasize on the atmosphere but I really don't mind it. ['cause I've seen worse and this isn't really a justify cause but lol]
Sound: 7
I believe they've focused on Butterfly a lot due contribution to the deceased artist or so I believe which is fine to my opinion. They still have other tracks which I did enjoy, and the voice casting was great, so I kept this as a 7.
Character: 6
Honestly I might want to give 5 for the original characters they've brought up in this series. They didn't give much explanation for why all these things happen, and thankfully they actually remembered to relate back the the 02 crew (barely).
The Adventure cast, well there's not much to comment on, they've just left the bonds the same since the original anime, so I felt this was the only good part that hasn't sunk (especially since the 3rd movie's reboot scene and this data restoration scene). Again, I believe they brought up too much for the limited space they have so potentials couldn't be achieved.
Enjoyment: 8 [This movie only]
I love the main Adventure cast and they kept to it at the very least, even though the plot was messy, I simply love it. I've still teared up a bit throughout the entire movie, and I had some good laughs, especially Patamon's bit.
Overall: 7 (6.5 for the main focus)
I won't recommend if you're the type to focus on the actual plot, or for the entire franchise. Rather, it's hard to recommend unless maybe you're not the type to care. I understand people's resentment to this movie series however to me... Well this is simply a childhood title that I can't really abandon even if it drags itself through the mud.
