The BSG one's my fav'. Short, sweet, and says all that needs to be said about the series (in a good way, that is!).
It is a great one, no question. I like how full to the brim the episode seems due to the "this week on..." shots are all from different eps.
Here's some more DS9 credits in other show styles...(Some of them aren't so awesome, but everyone clearly put in effort.)
