The storyline is incomparably better than previous series, in that, well, it actually has one(other than "collect the next thing!!"). It does take a few episodes to pick up the pace, but once it does it's engrossing. This series isn't afraid to be dark and this is greatly evident at times, but has plenty of lighthearted moments too. There are actual stakes in this series, in that if a Digimon dies, it's gone for good, rather than just turning into an egg five minutes later.
The characters are really great in this series. You really do get to care about all of these kids, and they do grow as characters throughout the series. Unlike in the previous seasons, these kids' problems aren't brought up and dealt with within the same episode- many of their problems are deep-rooted and take a long time to fix, if they are fixed at all. Overall, they are very human and you can't help but root for them. The Digimon don't change a whole lot, but at least some of them do grow in this series(Impmon mostly).
I'll be honest, the art in this show isn't anything spectacular. However, it isn't distractingly so. The character designs do a good job of conveying their personalities, and the monster battles are done really well. The Digimon designs are REALLY cool(come on, there's a rabbit with guns for hands and a ninja fox, what's not to like ;D), and the Digital World(which you get to about half way through) has some amazing looking areas.
I don't know what the music is like in the English version(apparently the English version was really heavily edited, with a lot of the violence taken out), but it is pretty good in the Japanese sub(and pretty good is a hell of a lot better than the goddamn awful that was the Adventure soundtrack). The OP is alright, nothing mind-blowing but still catchy and cheesy in a good way. The soundtrack is good overall, with one or two particularly amazing pieces.
Overall, I really enjoyed the show. It fixed all the problems that the first two series' had, while still retaining the epic monster battles, and the sincerity of the original that I had loved as a child. This show will make you laugh, cry, and care about the people and monsters in it. I couldn't recommend it enough :)
