Just today (Sunday) I got all the Infinite Crisis books and the tie-in titles just to see how bad they all are. After I read and review them (maybe review them - so many others have I may not have anything new to say) I'll put them back up on ebay and flog them off.
I mostly liked them. I liked the main series and about half the tie-ins minis, enough that I'm now buying the books that continued them: Secret Six and Shadowpact.I thought Infinite Crisis had flaws, but was still worth reading, and I'm keeping 'em. I'll be interested in seeing what you think of them.
