That's the thing - I can understand not wanting to have plot twists spoiled. A long time ago an episode of Beauty and the Beast was ruined for me that way, and I'm going to try to go into the last Harry Potter blind.

But to have fits over the cover? Unrelated images? It's a given that Harry Potter will be waving a wand or that Capt. Tightpants will shoot his gun. It's lumping the obvious in with spoilers that confuses me.
