You are talking about personal preference though, not an objective fact as such.
Of course. There’s no other way to do this. However, there can be objective reasoning behind subjective matter.
For example, villainy and benevolence make a good couple, but if the latter lacks the irony of conflict in its expression that makes it a good pair with the former, it just doesn’t mesh well.
For the lack of better words.
I think that’s the case with both Freeman and Pondsmith. They both sound like old history teachers, rather than something that could believably bend towards the afore mentioned irony to produce a good villain. They have a naturally warm tone to their voices which is hard to turn into ironically sinister.
If that makes sense to you. I lack the vocalbulary to explain it better.
For a reference, check out Tony Jay’s (may he rest in piece) voicework. He sounds quite similiar to Mike, but his voice ”bends” better for a villain.
