Thought W. was just dull and uninspiring. Brolin and Banks did okay with what they had, but I don't think they had that much. Thought the earlier stuff like the opening scene with the frat and the early courtship of the Bushes and the anger between father and son was handled better than the sequences once George W. was president.
Stone is one of those dispiriting cases because, while he obviously is a very talented/capable storyteller/filmmaker, he hasn't made a very good movie since 1995, in my opinion. That movie was Nixon, which I thought was great.
U-Turn in 1997 was pretty good.
Any Given Sunday has its moments.
But it's pretty telling that you have Wall Street, Platoon, Salvador, Born on the Fourth of July, JFK in the early part of his career and then W., World Trade Center, Alexander, Savages, and Money Never Sleeps in the more recent years.
