Good things about Digimon Frontier?

I see a lot of hate behind Frontier. While I do agree it was one of, if not the, weakest seasons I feel there must be some good from it.

My favorite thing was I really enjoyed the characters. Notably watching them develop and overcome their flaws. I like how they all had issues with forming friendships in different ways and it was by befriending one another they were able to fix the flaws. I always am a sucker for character development and I feel it had some of the best.
