I love SciFi, and I'm usually hesitant to make a Biblical argument against a work of mainstream fiction ("The Golden Compass" and "Harry Potter" not included!). However, reading through Larkin's "The Spirit World" opened my eyes to something that I think is important for Christians to understand.
In Transformers: The Revenge of the Fallen, Megatron, the leader of the evil Decepticons, is raised from the depths of the ocean (the "Deep," anyone?) to wreak havoc once again on earth. Of course, in the end the good guys win, but the storyline is filled with hidden Masonic references (Vigilant Citizen - Transformers 2) and NWO undertones throughout.
