Orcs was so bad I'd consider it, purely to save others from spending the money and wasting 10 minutes of their life. I bought it for $1, and that was too much.

The concept seemed cool, but who thought it was a good idea to have the prose come from the perspective of an orc as well?

There's a couple of books that intend to subvert history and give their readers a false interpretation of facts (that almost certainly stuck with them) in order to push their flimsy plot along, but I wouldn't ban them. But that's the closest I can think of damaging literature, besides the obvious of pushing certain agendas, which authors are entitled to do.
