Robert Redford directs this drab, but incredibly well-meaning courtroom drama about the lawyer who defended rooming house owner Mary Surratt against charges she aided and abetted Lincoln assassin John Wilkes Booth. The script sincerely explains how easily justice can be perverted in a patriotic fervor. The main actors (James McAvoy, Robin Wright, Tom Wilkinson and Danny Huston) are quite respectable, but the rest of the cast feels overstuffed with familiar and not entirely appropriate faces. (Justin Long? Really?) It's an important, moving and convincingly window-dressed drama, but the deliberately slow pace and unapologetic liberal tone make it feel more like a history lesson than a motion picture. FULL REVIEW:True-life historical drama teaches, preaches, with lots of speeches by Devin D. O’Leary (4/14/2011). 123 minutes PG-13.
