when i was watching over the weekend i was reminded of this post and just how often they say one "MUST" do something or other.
i think they did this in part to highten the sense of urgency of whatever situation they were dealing with.it just sounds more dramatic to say "YOU MUST!" rather than they less showy "you have to".
one "has to" pay the phone bill.but one "MUST!" burn a witch,stake a vampire,create artificial life.
another thing to consider is that the show was produced at a time when a proper command of the english language was still considered important.especially for a group of people who were,for the most part,well-edjucated members of the upper-class.good grammar and good manners mattered.
the way things translate from paper to the spoken word can be tricky too.the writers were trying to come up with good dialouge and perhaps didn't realize how it might play when spoken.i notice this with myself here.i try and articulate myself thoughtfully...but when reading the posts later they sometimes sound flowery and pretentious.
but i love how formally everyone on the show speaks.
