This has everything any comic book fan could want, it would even appeal to those who are not comic book fans, like myself. Just wanted to get it to see what other movies are coming out, since that seems to be the trend nowadays, make a superhero movie and you'll make a few hundred mil......but i was surprised by the sheer amount of superheros and super villains that exist, thought it would have been better if they went more in-depth with all the characters instead of just the better known ones. Overall, great encyclopedia.
