It seemed to me that the problem with Project: Superpowers was the tendency to just throw various characters out there just because they could, without any noticeable plan for what they might do with them. After several issues of "Oh, look--there's Amazing-Man! What's he going to do? Nothing much, it seems.", only replacing Amazing-Man with a different public domain hero every couple pages, it got hard to follow what story there was with all the "flash card" hero distractions. I think they'd have been better off if they'd just picked a cast and stuck with them long enough to make it thru a story arc, instead of leaving us with the sense of "Hey, we've got every Public Domain character we can think of--try and guess if we have a story to put them in!"
