Justin Roiland was replaced as Korvo's voice in Solar Opposites and many fans have said that they stopped watching because of it. I personally do not have an issue with the replacement, and understand why it was necessary. Dan Stevens takes over the voice role and the way that they address it is perfect. He does not try to copy Justin's voice, but rather gives Korvo a new voice. This did not change the vibe of the writing of the show either. It is still the same Solar Opposites, done wonderfully. I was not bothered by Justin leaving.
