If it's crap ... We'll tell you
Personally my favorite season is the third because it has a little bit darker tone then the rest of the seasons. What is your favorite season?
All of my favorite digimon are in season 1, but I did like season 3 as far as story development and the introduction of the card system which actually allowed the tamers to aid their partners.
The second season of digimon is my favorite. i like all digimons. All characters of childerns are nice.
Adventure is by far the best.
Scratch that: Only season 3, 1 and Adventures. The other ones are Ok, but there kinda meh.
Xros Wars (First and Second parts only)
Also, Young Hunters never happened. Ever. There were only ever two parts to Xros Wars, that third one was just a bad fanfiction. Don't let anyone ever tell you otherwise.
