I'd only ever heard of Captain Midnight in passing while researching HC books to buy and seen some of that Golden Age 50s(?) fare collected. It didn't grab me.
When Dark Horse announced he was part of Project Black Sky I was cautiously curious.
I love, love, love what they did with a character I really knew nothing about. It's honestly a bit of a shame he's a Public Domain character cause with how they crafted Captain Midnight he's a solid cornerstone character to their universe. I'm glad the run went 24 issues and if they bind it into an oversized HR it's an instant buy.

I was also impressed with what they did with the cheesy Gold Key character Brain Boy.
