Jim Knipfel does an excellent article on Godzilla movies and his fascination with them. He gets into why he loves them, why they are so much better than people realize and what inner meanings they may have. He also delves into what it's like being a Godzilla fan.
If you're an allegedly intelligent, well-educated adult and you mention Godzilla in mixed company, people look at you like you've just admitted that you have syphilis. They immediately assume that you're one of those pathetic creeps who lives in his mom's basement, spends hours every day arguing Lost in Space minutiae in chat rooms and goes to conventions in New Jersey dressed like a Wookie.
Knipfel, by the way, wrote a fun novel called The Buzzing. The book is about a reporter at the bottom of his life stumbling onto a conspiracy. Strangely enough, that conspiracy has everything to do with giant monster movies. The book is good for any one who's interested, but there are so many references in the book to monster movies, that a fan will have tons more fun with it.
