If we're talking Digimon-things you should (or shouldn't) watch, I cannot recommend „Digimon X-Evolution“ enough. It's a 3D-animated movie that's completely independent of all other shows and movies, it features a storyline that was popular in the card-games and other merchandise at the time, and because of that it has some similarities to later shows, with Savers in particular because of Yggdrasil and the Royal Knights.

The beautiful thing about this movie is that there are no humans in it, it's a story completely focused on the Digital World and features only Digimon as protagonists and antagonists.

It's a fun little flick to watch, you can find it on the net with English subs relatively easy. I think it's even on YouTube.
