Intermittently interesting, but suffering from a multiple personality disorder. Some of the charts were helpful and interesting explications of some aspect of superherodom (e.g. the time elapsing between a major character's death and their eventual resurrection) while other charts were just plain silly (I can barely remember the silly ones, but they'd be a picture of, say, Captain America's shield, with a legend claiming the white parts are the amount of time spent attacking, the red parts are the amount of time spent defending, and the blue part the amount of time spent resting. Not helpful, not true, and someone who makes charts should know humans are good at seeing difference in length but not area!)
(Note: 5 stars = amazing, wonderful, 4 = very good book, 3 = decent read, 2 = disappointing, 1 = awful, just awful. I'm fairly good at picking for myself so end up with a lot of 4s). I feel a lot of readers automatically render any book they enjoy 5, but I grade on a curve!
