There are some comics that really need to come with a warning label. Labels like "Remove brain before reading" or "Attempting to understand this comic could seriously damage your sanity".
Some of Grant Morrison's more surreal works can give you a headache if you try to make sense of them, but Morrison at his most peculiar rarely comes close to the distilled nuttiness of Roberts Kannigher and Haney. I've just started reading the Showcase Brave and the Bold collection and I'm not even to the end of the first story and I'm looking for some asprin.
The first comic in the collection is a time travel story written as stream of consciousness. Cause and effect are not only reversed and sent sideways, but retconned three pages later to be a flock of hammers. Important story elements are added as required without any effort to integrate them earlier in the story. People use ill defined powers to do unnecessary and bizarre things. And it is absolutely stuffed to the gills with sense of wonder.
It's difficult to get yourself in the right frame of mind for this kind of comic. It doesn't have the clever, sophisticated stuff we look for in the medium nowadays. It doesn't have complex motivation or political subtext. It has no repurcussions beyond the final page of the story, and nobody's world is changed forever. But if you can read it without adult preconceptions of what makes a good story, or even makes sense, you could have a really fun time.
I'm looking forward to the rest of the book.
