Whoa, that's some seriously harsh words
I've got to watch the movie to see for myself 
I have always been more into manga than anime but I remember watching an anime version of some manga where the character I more or less liked got a horrible voice... Well, to me 90% of anime is unwatchable because of voices of any kind of character.
Can you please give some more examples of those you hated if you remember? I want to see that to avoid that. (My comic is completely sketched out already but if I had done some horrible mistake, I want to change it!)
Yeah, that's also what I use Purra for - I hate soliloques and a silent animals are good for characters voicing their thoughts without looking weird 
I gotta watch the movie with Koromaru, I hope he's as cute there as he's in the game (I don't play games but found out there was a movie).
Thanks for the feedback on Zeero. I myself probably didn't know what to do with him - first he was just an accessory to show that Mirrage is a hobo but then he came alive and became somewhat of a mentor to Mirrage to make up for what he was lacking to survive
...Man, I really haven't thought about these characters for years, I almost forgot what it was about >_<
That. Was. Weird.
Maybe the fishes might have worked or the turtles... I honestly don't know if I should laugh or cry >_<
(I didn't know Pikachu could talk)
But at the same time, watching the video without seeing the whole episode/movie and being attached to the characters is a totally different experience, I believe it worked for long-time viewers.
It's the same as discovering a new comic and first landing on a page where someone is bawling their eyes out. You first think "What the hell, such stupid drama" but if you read from the beginning and start to feel for the characters, the experience of reading that page would be different.
This is an issue with webcomics in particular because people get to read like a page per week and when there is a serious sequence going on, people reading it page/week would find it disconnected and hard to feel for than the readers coming in late and reading it all at once.
...Yeah, another thing is when a comic has a very active fanbase that keeps commenting things like "don't make her cry!" and often make the whole scene more dramatic than it was meant to be 
@Jelw Yeah, when they talk they more or less become a separate character that needs to be handled more carefully than an "accessory character".
