We almost went to war in 1962, but President Costner prevented it!

Rating: Null/10 (8 December 2009)

The problem with letting people star in and produce a film- especially an historically based picture - is that the tend to skew the story towards them - their character.
While it's said how the script's dialogue is almost 100% fact - as Kennedy (and ...other) President's recorded their conversations, it still comes off as another 'Kevin Costner is our Saviour' picture (see- Waterworld, The Postman, JFK, etc).
That's exactly what happens in THIRTEEN DAYS. President Kennedy is portrayed as almost Kenny O'Donnell - the character Costner portrays - puppy dog.
While I'm not taking anything away from the importance to advisers in any field, you can sum this picture up by saying; thank goodness for President Costner, er Kenny O'Donnell....
