i got hooked on this show in the first 15 minutes of the pilot. james franco's character travels back in time (in particular 1960) to prevent the assassination of JFK in 1963.

if you're a sucker for time travel, the butterfly effect, chaos theory and all of it's implications then you're gonna love the show. bear in mind that this is not scientifically accurate by any means, but it's a show, not a scientific paper.

apparently 11.22.63 is based on a book of the same name which i haven't read, so can't confirm whether it follows the book or not.
