Say what? Books are NOT dead. If they were - would the movie industry have to keep making them into movies instead of coming up with original content? Come on, they turned fan fiction into a trilogy (50 shades is somehow fan fiction of twilight).
Saw the 1st 2, will see the last one eventually. Suspension of disbelief. It's entertainment, not to be taken too seriously. WICKED is the name of the bad guys.... eat the eye candy and be happy.
