I have a detailed review of A Fallen Star for All at my blog. Review is based on my playing as a player and purchase/reading the module.

I like what they did with DCC. A slow page-through of MCC left me feeling like it was rather short in some areas. Well, DCC also felt like it had some content holes but it was still pretty huge.
Perhaps the MCC supplements help?
I'm a bit overloaded with good post-apoc stuff anyway (Mutant Year Zero, The Mutant Epoch) , so I drag my feet further. :))
