The title of these series of course refer to the date of the assassination of JFK. There is only one season of eight episodes which are written by noone less than Stephen King.
Jake, a high school teacher, learns from a friend who owns a diner that there is a door to 1960. When somebody comes back to the present, only two minutes have passed, no matter how long he stayed in the past. Al, the friend, took up the idea to prevent the assassination of John F. Kennedy and collects all the information he can find in the present and in the past and went ‘in’ several times only to come back without succes. So he asks Jake.
Of course when you want to prevent the assassination, you will have to spend a few years in the past. Most of the series are Jake in the 1960’ies try to blend in while trying to find a way to try to find a way to do what he came to do. When he succeeds, the result is not what he thought it would be though.
The series have some alright findings and things to think about, but all over the line it is not much more than a drama about a contemporary man trying to live two decades ago.
