I agree that BOL was boring. I don't think it was an actor's movie either. I think it was trying to be an edgy deconstruction of the CIA's role in the post-9/11 world, particularly the Middle East. But it felt overbloated, overly convoluted, underwritten, and--worst of all--boring.
However KOH DC is worth checking out. Fox forced him to cut a 3 hour epic that may not have been great (Orlando Bloom wasn't strong enough of a lead to reach greatness. That movie needed a Christian Bale or Ewan McGregor type in the role) but it got pretty close. And had amazing supporting performances by Liam Neeson, David Thewlis, Jeremy Irons, Eva Green, Brendan Gleeson and most of all the Syrian actor whose name escapes me right now and Ed Norton as King Baldwin IV (The Leper King).
Just to illustrate how better it is...the priest Balian kills at the beginning of the movie? Did you know that was Balian's brother? Or how about why did Sybilla (Eva Green) go crazy at the end for no apparent reason other than her husband being a predictably terrible king she could not control? Because before her husband ascended the throne her son (who you never see in the theatrical cut!) becomes the Boy King, however it is discovered he too has lepracy and instead of letting him suffer, she kills her own son, dooming her kingdom in the process!
It is a much more meaningful film.
