Usually when the good guys win, they live. In this case, the good guys were shot and killed and died. Apparently C J believes in an afterlife. Good for the good guys. The good guys were suffering angst. Seems their death provided peace. Still it was a happy ending. JJ went back to the ranch. Possibly being joined by Monica. The loss of their loved ones was sad. But their lives seem to be healed. Very interesting ending. Pretty cool.
