Hmm, I hate it when people find Firefly dull, because I just don't understand how they can. That's nothing against you, HotRod, and I really hope you get into it. But like Chaltab said, Serenity ups the ante about a hundred fold.

Adam, I've never heard of an opening narration sequence. The DVD extras contain the prototype opening scene that Joss originally planned to use, but it doesn't have any narration, either. Serenity (the movie) starts with narration, but that's the only time that style of exposition is used (unless you count Tracey's recording in "The Message.")
