Top critical review

Short ? yes, it's little more than a pamphlet. quite a few pages have about 12 words on and massive cartoons. abstract concepts, no specifics, i saw nothing useful in it, although i was so irked by its lack of content for the price that i only flicked through it before discarding. others may approach it more generously than i did if you can borrow a copy. anyway, i sent it back for a refund, there is better stuff on the web for free.
