Today, I was fortunate enough to get invited to a screening of BHD here in LA that had a question and answer session with Bruckheimer and Scott at the end.  
Without going into too much detail, this is a must see movie.  I was a little leary with Bruckheimer being involved, but it was AWESOME.  It was every bit as good as the book (though there were some differences, mainly due to time constraints).  I can't recommend this movie enough.  I plan on going to see it again.
