Unique dialect add some life in the environment, not just an individual. Cohesive, and richness in social interaction, in term of massive variation though. In the bad side however, like most have covered, they lack depth of character. We can call that social gone wrong.
Regardless, I still think unique dialogue and more coherent dialogue should be what they have write. I like some of the accent, and some are annoying, but majority of them are neutral IMO.
I love the fact that Draggy got ''extended accent''. Dragggyyyy, it add some cuteness isn't it, just like his nature should be.
I also have no problem with Harle accent, just neutral. Her role and appearance in most of the scene are memorable, thus prevail her accent.
Although, I have some hard time with whoCHA did you refer?
Just go away to hell .......
