It's a very simple system. The rules portion of the book is about 3 pages long with the bulk of the book describing the different powers available. As it's drive thru entry suggests the total book length is 30 pages.
If you are looking for a skeletal framework for a superhero game (on the cheap), this could work for you. If you want something more substantial there are plenty of other options out there.
