Just watched the first episode of the latest season, and wow, am I ever impressed with those writers. Somewhere around season 3, I was about to give up on the show, it seemed like no one really had a clue where the story was going and nothing was ever getting explained.
But then I stumbled on a site with a theory for it all... time travel, and all of a sudden, many strange things suddenly made a lot of sense.
"When are we?"
"Well John, that's all relative."
I love it.
The vision that the writers had from the start must have been huge. It's taken a very long time for them to explain a lot of strange things from episodes that aired years ago.
