Well, the title of this movie pretty much tells you the main character is assassinated and it also tells you who does the assassination.
First thing: Very Long Movie! Past midnight for us. At any rate, Jesse James is the bad guy robbing trains, banks along with his brother Frank. By the way, this movie is based on the life of the real Jesse James. Jesse, was feared by everyone. At the beginning of the movie, we see the James brothers robbing what it seems to be the last robbery for Frank (Jesse's older brother), then he decides to retired from it. Jesse is left on his own with the gang who still wants to support Jesse. The police puts a warrant for Jesse's arrest and a prize for his head.
This is where Robert Ford comes in to play portraying Jesse as his long time hero. There is really nothing I can say that will spoil this movie for anyone reading this lousy review, other than the fact of why Robert Ford is called a Coward. It is interesting to see how everyone wanted Jesse dead and after his death he was idolized. The question is why is Robert Ford seen as a coward? Well, you must see the movie to understand it and I won't spell that out here. It was a sad ending. They almost got me convinced Jesse James was the good guy. Almost.
If your faith is strong, watch this movie.
