I liked the digimon that appeared in data square the story so-so. 
The last season of digimon the one with the time travel......has a serious lack of time travel for my taste. XD
I mean if you make a big deal about the old digidestined gonna appear in the show then at least give them a few more episode of interaction. Wouldnt have minded if beside the main main some more got a bit of a spotlight. XP
