Morty's voice is fine. Most of Roiland's periphery characters are fine. Rick is mostly fine, but the little eccentricities of his voice have largely been washed away. The burps, the little idiosyncrasies, and it gets really obvious that the alcoholic rasp is gone when he starts yelling. It really sounds like an AI Rick voice and I'm starting to wonder if they're using an AI to generate the voice and crediting some nobody since AI is a hot button issue at the moment. I think the unsaid part of this whole kerfuffle is that it's a referendum on whether or not a show can lose its flagship star and keep trucking along without people noticing too much. And if they see they can get away with replacing the voice of someone as popular as Rick Sanchez, it's going to be a bad sign for things to come. If this works, I'd expect to see a wave of people gettng cancelled in the aftermath since they no longer have "too important to lose" status.
