Free Comic Book Day is a good time to reiterate a certain point that I feel fairly strongly about. Yes, the movies based on the comics are great (no, haven't seen Age of Ultron yet!) and the other comic-based products are fun (the Arkham Asylum videogame series has been a hot topic in our house lately), BUT... I think it's really important to remember the COMIC BOOKS.
The comics are the roots and the origins. The books present the special and unique sequential art. So when you're embracing the comic culture, don't neglect the foundation of the industry. Show some love to the writers and artists... go buy a comic book.
