Worst voicing in a cartoon ever!

Rating: 2/10 (12 January 2019)

I don't want to judge a book by its font, but voice of mother (by Holly Hunter) is annoying as hell! What the hell?! Who thought it was a good idea for a main character to be voice by someone with a speech impediment. It sounded like she has her tongue is frozen and she can't move it. The best comedy in this cartoon was when she (for what other reason) was brushing het teeth and saying something! If it's not a rude joke on the actress for her inability to speak clearly and not annoyingly, I don't know why this scene is even there.
This who cartoon was okay, but if muted for the most part.
I'm sorry, as a person I can't listen to this voice, especially in a cartoon. Worst casting of a role I have EVER heard.
