Oh God, Gennai. I somehow blocked that out of my mind completely. Ugh, you'll see.I've only seen the first movie of Tri so far and...other then having some of the original voice cast back I was underwhelmed by it. From what I hear of future events they spit on the 02 cast. I'm not a huge lover of the 02 cast but that is so disrespectful to that season and those characters.
I also didn't like those adults that were working with the team. The Digidestined answer to no one but Gennai. I didn't even see him in the Tri movie, but I'm sure they mention him in future ones.
That said, the other adults, there is a point to them revealed in time.
