People who complain about the spirit world in LOK being too colorful and whimsical always cherry picks only scenes of colorful place, but continently leave out the Fog of Lost Souls and the dark forest Korra fell into.

They have just shown more parts of the spirit world that was not seen before, it didn’t erase the ATLA style dark and drab spirit world, it just added more Locations that are more diverse and includes both dark and colorful locations.
