KH is an ARPG with a very kinetic, fluid combat system that I really like. The gameplay of the mainline games is top notch. If you like fluid, combo based combat with a happy, bright aesthetic, there's a lot to like here.
The plot isn't appreciably more convoluted than most games, the problem is that it's spread out among a shitload of different spin off games on a magical rainbow of different handhelds. However, the details these contain are either largely disposable or only related to side bosses you probably won't fight anyway unless you're an insane completionist. And if you do care, most of it is now available for PS3 in the 1.5 and 2.5 bundles.
If you're expecting new insights into Disney characters, though, you're probably going to be disappointed. Most of the Disney stuff is abridged rehashes of the movies with tiny little adjustments to force them to fit in with the story of the game. The only world plot that's really noticeably different from its source are the KH1 versions of Nightmare Before Christmas and The Little Mermaid, and the KH2 version of Beauty and the Beast. Everything else is 90% rehash.
You will miss out on some "OH HEY IT'S THAT GUY" moments by not having played the 90s Final Fantasies first, but that's not a huge loss.
