Disappointing. Less flamboyant than the trailer promised, possibly something to do with its length. Too often scenes went on just a bit too long once the situation/relationship/dramatic point had been made. They were not excessively overlong, scene by scene but when this occurred almost all the time, overall tempo and audience involvement in the action tended to flag.
The earlier part of the film was more gripping as the family was revealed but then tension was lost and certainly after the assassination and the aftermath, there was definitely a rather cursory air to the proceedings. But it did look good and the performances were pretty fine.
