I would agree but my whole ambition is for straightforward communication. So, if I'm to treat Star Trek as the future people bring straightforward is high on my list of wants in a show.I understand what you're getting at here, but theatre isn't the same as cinema or even TV. Sets are much more rudimentary, the camera doesn't exist, most of the audience can barely see the faces of the performers, etc. Everything has to be based on dialogue (and, if not that, monologue).
Even with that, I'd say that while Shakespeare has characters spend quite a good deal of time talking about their feelings, they're not straightforward. All of Shakespeare's most famous tragedies, from Romeo and Juliet to Othello to MacBeth to King Lear, are based upon miscommunication.
Sadly, Trek fails at that and other shows do it far better.
