>>212217524Would you rather have 100 literal whos or condense them into one actor to play the part? Some random face says "hey that's a lotta Roentgens!", another being like "uh, yeah it is!", then a third and fourth being like "they're absolutely right!", or just one person saying the same thing in one line? It's a 4 hour long series. They needed a face to put on the team, not 100 random scientists yelling things to get the point across to the audience. It was both practical and good writing for the audience to comprehend what was happening.
