I realize that, but it was a pretty lame spell that doesn't really show how no one besides Richard ever broke out of it. No one can ever break the spell of Perdition... unless they really love someone like Richard did so would know the hallucination isn't really. Obviously no one's ever felt such true love like Richard. The corniness of it all makes me want to barf.
However, now that I think about it, it's a bit silly to criticize the TV show for a Richard-based deus ex machina -- unless I'm complaining about it copying Goodkind's theme. The obnoxious ending of NE is barely readable.
