#1 according to the creator. The movie was where the shipping wars came about. That movie I think I'd prefer Taichi and Koushirou together than Taichi and Sora.
I don't mind the ship, I just don't see it. The only people I definitely ship are Daisuke and Ken. I mean, seriously? They were just.... Wow. I don't get the Miyako Ken ending because Miyako seemed to like him as a fangirl and then everything changed when the Digimon Kaiser attacked (haha). Of course, there were years for stuff to happen, so I hope Adventure 05 tells us about this more
