It's not that it isn't obvious, it's that it just doesn't work. Being left to spend your retirement years in paradise with your family and best friend isn't exactly "punishment."I always thought that was really quite obvious in TWOK, I'm surprised to see so many people are confused about it.
Have you learned nothing from The Menagerie part 2? Humans don't like forced confinement!
I thought both of the screams were silly. Shatner's was just scene chewing, and I can't watch it without either laughing or rolling my eyes. Quinto just didn't sell it. It's an over the top moment (good or bad), ya' got gnaw on the scenery and blow out a lung; he just didn't throw himself into it.
Maybe that's because such screams are silly and don't normally happen in those situations?
