If I wanted to kill hour and half of my life by learning and solving nothing, I would have watched Lost back in the day. Don't get me wrong, it was funny and full of action, River Song is made of awesome, but that's it. Nothing was answered, more questions were asked, more mysteries presented. It is going to end like The X Files or LOST - in the end there will be no one knowing what is going on, including the creators. Or it'd be complete disaster like The Big Bang. Argh.
