@Tartar-For The Road I’d say the book is better, but the movie pretty much nailed everything in there…character images and all. Book, however, is much more depressing.
Lucky Number Slevin is really a one time watch movie. Once you watch it once you can’t watch it again, not that it’s bad or anything, just because of the way it was written with all its plot twists.
And since you seem to the Grammarphile type maybe you would like some humorous books on grammar? Such as Eats, Shoots & Leaves, or Things that make us [sic]?
