If you’ve never seen, this is comic geek heaven.
One of the things I loved about the FRINGE series is that events of the final season tied back to previous events of the series, all the way back to the first season. It made me feel like JJ Abrams wanted to tell a complete story and avoid the mistakes of previous shows like LOST and X-FILES that failed to resolve plot points. The finale was a reward to faithful viewers instead of yet another unsatisfactory disappointment.
