Story 10/10: Digimon Tri is exactly what the Digimon fandom needed. Back in Digimon Adventure 02, when they brought in a new generation of Digidestined, whenever one of the original characters showed up in an episode for a crucial plot point, we saw exactly how much they took their crest to heart and how that helped shape them as they grew up; here in Tri, we see the original Digidestined start to struggle with who they once were and who they will become. From the way part 1 and 2 came out, it seems that each part is going to feature 2 characters per part struggling to remember and recapture what their crest once represented about themselves. Something to know going in, they use the first part of episode one to "subtly" let you know that the new digidestined from Adventure 02 WILL NOT be featured in (and possibly not even a part of) Tri.
Art 9/10: The art will probably be the toughest thing to adjust to if you still have the animation from the original series in mind, that being said, you will probably come to love almost all of it after that brief adjustment period (even I still have problems with some of the CG art during the digivolving sequences, but that's also mostly just Ikkakumon). Once the show finds its footing after two episodes, the fights also all become amazing (look forward to the final episode of each part for epic battles). Despite how Tri shapes up in terms of art, what keeps the art score away from perfection in part one is that they keep reusing stock footage in flashbacks (trust me, you'll see what I mean).
Sound 10/10: Miyazaki Ayumi - "Brave Heart" enough said.
Character 10/10: If you thought you knew the original characters after 2 seasons of 50+episodes, you are wrong. Tri takes their character development to the next step now that they are older and have their futures to worry about, as well as how they now realize that the Digimon cause real damage to their surrounding when they fight. Like I said above in plot, Tri has a major focus on the original digidestined recapturing what their crests once meant, and so far, each is done beautifully (part two better than part one in my opinion). The relationship aspect that we couldn't explore back in the original series because of their age is also starting to be addressed in Tri, which may trigger some people who have longtime ships from when they were kids, but it had to happen eventually (and I swear, T.K. better shape up and realize he is meant to be with Kari).
Enjoyment 10/10: This was exactly the nostalgia trip I needed in my life, and seeing as I don't do drugs, that is the kind of trip I am always down for.
Overall 10/10: I'm so glad that they found a way to add on to the series that I grew up with as a child so that it can continue to have meaning in my life later on now that both the characters and I are older. If you want a repeat of the series you also once new as a child, let that feeling go for a bit so you can take in what Tri is trying to do.
My only complaint is that there is only one part (4 episodes) released every 6 months.
