You go to digimon for the story - the plot. But the plot wasn't there. It's something you can marathon, and tends to be something that's hard to just pick up and drop. Pokemon, on the other hand, is the exact opposite - pokemon is designed not to be marathonable, but rather to pick up and watch as able. It's perfectly okay to grab an episode or two and drop out for a while, and is quite accessible for that.
What Hunters did is take Pokemon's approach, something that not only turned off a lot of us digimon fans, but downright felt like an insult to those of us who've had to defend it against "lolpokemonclone" over the years. With only 3-4 episodes for plot, this could have easily been condensed into a movie - that leaves 18 episodes for filler.
Personally, I wish the teams were different too. I disliked Tagiru quite a bit - moreso than Daisuke from 02, which I didn't think possible. However, I did think Yuu and Airu had some decent chemistry, and I really liked the chick from the ghost episode. I'd love to have her as a hunter and have those three team up...
Still, the biggest problem with the series is that the plot took a back seat, which really is a very un-digimon like thing to do. I'm sure if it had been more in the forground and if they had done more with the new Xros mechanic, it'd be amazing. I mean heck, Tagiru didn't even use half the mons he hunted to Xros with... so much potential for this show... wasted.
That doesn't mean Hunters should go to waste, though. It's setup is amazing, which lends it to be ideal for RP and Fanfic communities - and let's face it. Even they will tell better stories with it. There's quite a bit to take advantage of there after all.
