After Firefly was canceled there were some loose ends that needed to be done and Serenity did that.

So, what other TV shows would you like to see a movie (or series) that closes the loose ends?

I vote for the Wire. Even though each season was its own story arc the last season left some unanswered questions. For example, what happened to Jimmy? I won't say more to avoid spoilers.

What do you think? I'd like to avoid spoilers so I suggest you keep it general when asking what happened.
