First of all, this book is probably a great buy for Hulk fans if you want some background on the Hulk in comics, TV, animation, and the new movie. It also includes three comic stories- the first Hulk story, a sample issue of the current series, and the issue of the Ultimates with the Hulk. However, anyone looking for a repeat of the terrific X-Men Encyclopedia, or even the mediocre Marvel Encyclopedia Vol. 1, will be disappointed, as there is VERY little encyclopedic information. (One reason I think it's a bit unfair that it's shrinkwrapped- in stores, you can't tell what you're getting.) The Hulk Incredible Guide by Tom DeFalco is MUCH better for that.
