The addition of challenged books makes this anything but another boring book category. If you look at the most challenged books between 2000-2009 you get titles like the following:
Harry Potter Series
His Dark Materials Series
The Perks of Being a Wallflower
The Lovely Bones
Snow Falling on Cedars
They're slightly more modern in some ways, but you also get authors like Judy Blume, Robert Cormier, Katherine Patterson, Madeleine L'Engle, R. L. Stine, Garth Nix, S. E. Hinton. Some of the titles are classic Young Adult reads.
Start going into other decades and you actually get some titles by Stephen King like Carrie, Cujo and The Dead Zone.
I don't think the exercise has to be a drag. Even The Da Vinci Code has been a banned book in Lebanon. Of course, I might well think that reading The Da Vinci Code is a major drag, but it is in the thriller category.
