An interesting "what-if" story: a man from the future goes back in time and prevents JFK's assassination. This movie presents an optimistic view of how history turned out. The narration follows three threads; our time, following the death of JFK at 84; the presidency of JFK after Nov 22, 1963; and the Kennedy's involvement in the life of a young artist. Bruce Campbell does parody again, it's nice to see Ralph Waite, and Larry Drake looks like he may explode soon. Like any good time-travel story it leaves you bewildered at the end. It's a bad political history, though, and I found much of it unbelievable. The conservative Republican revolution would have happened anyway. The oil shocks of the 1970s would have happened anyway. Sure, Dan Rather stays in Dallas and the Beatles never break up, but whatever happened to Nixon? What happened to Barry Goldwater? What would have happened to Vietnam?
