Well, he certainly wasn't good in Jumper either. Or Awake.
I found it funny that Shattered Glass has him portraying Stephen Glass's rise through an American Magazine called The New Republic
As for Kasdan, I'm sure he'll do a stellar job. Three Lucasfilm releases under his belt and he wrote, directed and produced Wyatt Earp, which isn't as good as Tombstone apparently but I love that film. At this point, without a director or vague idea of a plot, writers and producers are pretty meaningless to me, just names helping the rumour mill going round.
