What happened behind the scenes in RHI?

Kevin Costner hasn't promoted this film at all, and hasn't said a peep, other than a couple of interviews with Pat O'Brien of "The Insider" earlier this year.
It's true KC has been busy filming "The Guardian" in Louisiana. This is the first time he's missed a premiere of one of his movies.
I wonder, though, whether the events of last year - that false story planted on a website about KC allegedly being responsible for director Ted Griffin's firing, Griffin's replacement with Rob Reiner and Reiner's reworking of the script - also had anything to do with KC not being at the premiere or doing any promotional work for the film.
Meanwhile, the critics are mainly doing what I expected them to do when this project was announced last year.....Holding this movie up to the shrine they erected to the 1967 film "The Graduate," and finding it lacking. Most of them, though, have applauded KC's performance.
I plan to see the film this week, and then I'll write my own thoughts.
