I passed on the single issues but the collection is great. It's only issues 1-4 (so more expensive than single issues) but it is spectacular. Easily 6.67x10^27 times better than infinite crisis.
The story is self-contained (yay!) spectacularly illustrated and the plot is chilling. The final fight where Bizzarro, Parasite, Solomon Grundy and Metallo jump Superman is one of the most epic fights I have seen anywhere. Bizarro kidney punching Superman was just so well done.
So strong, strong recommend!
