There is that nostalgia thing going on, and I don't deny that.
I also think it's got a lot to do with Japanese media in general and their simplicity with character types. Starscream has a booming voice, as does Desslok from Uchu Senkan Yamato. Its because they are easily identifiable as a bad guy. Personally I much prefer Desslok's slightly whiny English voice as it adds way more character and stops me from immediately assuming him to be a shallow stereotype. Even though he may me.
I'm also glad that someone else noticed they go the fusion cannon sound wrong too. I thought it was just me and I was being snobby. So, thank Sinner!![]()
