Every now and then as I watch a show, questions such as these pop up in my mind: Where have I seen that actor before? Hasn't she already appeared on the show before as another character? What is that song playing in the background? Where has (insert character name) gone? And on and on.

I also have questions about current shows even when I'm not watching them: How many episodes will we get this season? When will the season premiere? Will (insert actor's name here) be back on the show? Which famous person will guest star? And so on. That's not counting the questions I have about upcoming storylines! Thank god for spoilers!

Of course, questions about series from the past also pop up: Why did (insert show here) end? Can I get answers for the unanswered storylines since the series was canceled without having a proper goodbye? Whatever happened to (insert actor's name) who played on (insert show's title)? And so on.
