A comic you thought you wouldn’t like, but ended up loving.
I had heard that Starman was good, so I bought the first trade and was not very impressed. I found the new Starman, Jack Knight, whiny and lackluster. But I usually give a series more than just a single opportunity to impress me, including collected editions, so I bought the second volume and I was less annoyed. This led me to the third volume, and I was hooked! What a great series overall, especially the world building that James Robinson did with Opal City and everything he put Jack Knight through.
