Are you watching in English or Japanese, by chance?
English. Digimon is one the few anime I absolutely can't watch in Japanese. I've tried multiple times. Last time I rewatched it, I actually went through the first few episodes in both languages before I just gave up and dropped the sub.
Data Squad's pretty good once you get past the first 11 or so episodes. And as for Tamers, the first half isn't really a big problem; it's more when they go to the Digital world. Almost their entire time there is spent getting lost and looking for each other. Thing's start getting on track when Beelzemon shows up, but then there's the D-Reaper which I feel goes on a little longer than necessary.
