This is a very sad story.
I do think Klingon house politics are not everyone's cup of tea.. though picking a character from TNG was certainly a good idea. It's hard to pick a random ep with DS9 when the viewers have no background. The Magnificent Ferengi might seem like a good starter ep because of the pace and humor but you lose a lot of if you aren't already familiar with Vorta.
How about The Visitor?
