Fringe goes out on top. Using time travel to fix the ending is a timeless device of Sci Fiction. Fringe played it beautifully. The whole season developed the ending. Fringe really had two concluding seasons. First the war with the alternative universe was concluded when it looked like a season five was a fantasy. Then a single season focus on the war with the observers was developed when some accountant probably figured out Fringe will be a classic and five seasons are needed to give it some push. The end of Fringe is also an end of an era of great sci fi produced for the small screen. Dystopians with or without alien invasions are as much of a procedural as cop shows. What I would like to see next is a HBO type project bringing Harry Harrisons Stainless Steel Rat to life. Kim Stanley Robinson Mars trilogy is also just waiting to be harvested. Similarly Peter F Hamilton has a good 20 seasons of quality work that only needs money and love to become something special in the zeitgeist.
The last image of Fringe is the drawing of the White Tulip, a symbol of redemption first seen in episode 88. Walter mails it to Peter. It’s a message of hope and faith that somehow navigates through a time paradox. A white tulip to JJ Abrams, with Fringe you restored some of the fabric of the universe of disbelief ripped asunder by LOST.
