And you should definitely pick up the comic. Sure, the movie may have all the eye-candy explosions and mad-skillz knife fights, but I definitely think the story is much easier to follow in the comic. Or at least more in-depth when it comes to everything going on outside of V's Shadow Gallery.
Only in the movie, dear! In the comic, V uses his knives, along with just about everything else he can use to kill people. (Comic-V also uses tear gas, cyanide, and an exploding fake hand. The knives come out maybe once or twice.)
