It was OK-ish on its own, but the series shoving anything 02-related to the side causes lots of continuity snarls.
For one thing, the series treats Digimon as if the public has never heard of them. Never mind that Myotismon had a very public battle in Season 1, the Digital World appeared in the sky around the world soon after, Hundreds of people saw Omegamon fight on the Internet in Our War Game, dozens of DigiDestined helped the main characters fight very public battles in the Digimon World Tour, and hundreds more were given Digivices after Malomyotismon was defeated. You can't cover up the existance of Digimon anymore.
Speaking of 02, not once in any of the episodes did any of the 01 kids even show one iota of concern or even mention the 02 guys. Even if they don't know they fought Alphamon, shouldn't they have tried to contact them at some point? And why does Not-DATS not tell them about the 02 kids?
Also found it kind of lame that MetalGreymon, WereGarurumon, WarGreymon, and MetalGarurumon appear with little fanfare. I mean, the new evolution sequence isn't great (and has 0 connection to the original sequences, another annoyance), but I wanted to see a new Warp Evolution scene...
EDIT: Also, I find it funny how Takeru wonders how they will get home when in Season 1 they all just rode Ikkakumon or Kabuterimon everywhere.
