A nice curiosity book
Okay, well this is definitely one of the mediums classic stories. Does it deserve to be at the level of say maybe the Watchmen, or even Arkham Asylum? No, I do not think so anyway. It works as a curiosity, but the story itself is really simple and it just does not make sense if you apply any real knowledge you have of the Marvel Universe.
As a curiosity though, it is fun to see the way the writers came up with for Frank to kill all of the earths "heroes and Villains". Hired by those who would be considered collaterall damage by the heroes to take revenge, they bank roll the Punisher, and keep him out of jail when necessary.
It is an exciting and fun book that could never happen. Take it as a what if, and leave your brain at the door. Good Times are to be had here.
