CP and I went to see Doubt last night. (Thanks Gabe! Thanks Chris!)
Though their cast had characters well acted, except for maybe Amy Adams who I felt was still playing the part of a princess playing a nun, I felt that this is a story better not taken off the stage. The fact that it's on the silver screen instead of a theater stage distracts away from the dialogue.
(See also: Glenngary, Glenn Ross - except GGR survived the jump from stage to screen.)
