Stephen King is no stranger to having his books turned into miniseries. Some, like It, are considered classics. Others, like The Langoliers or the 1970s version of Salem's Lot, are kind of cheesy or even plain terrible. Still more, like the Steven Weber led The Shining, which is superior to the Kubrick film (Not sorry. That movie is awful and dull.), will never get their proper due. To me, most of King's works are told best in long form. It gives them room to breathe. This doesn't take away from the amazing features made from his books, but sometimes miniseries is bettah. See what I did there? I'm hilarious.
This is the case with 11.22.63. My wife and I just called it the Franco show, because while the numbers make the title look short, Eleven Twenty-two Sixty-three is a mouthful. The story is interesting. What if you could stop the Kennedy assassination? That's the task diner owner Al (Chris Cooper) gives to his friend Jake (James Franco). Al has tried many times, but every time he gets close, something goes wrong. Now he's at the end of a losing battle with cancer, and he's passing the torch. A portal exists in the back of his diner, and when you walk through it, you're in the same spot exactly three years before the assassination. Whatever you do in the past becomes part of the timeline when you come back, but if you pass through the portal again, time resets. This comes in handy if you screw up.
