I find myself agreeing with Franta twice in one week, incredible.
I thought Tomorrow Stories was pretty weak in general, I lost interest in it early on. However, Greyshirt was fantastic, and gave me more reason to believe Rick Veitch is a genius.
Tom Strong is my favorite ABC book, it's the first thing I read every time it arrives(which isn't too often these days), and I'm shocked that some would consider it the weakest of the line. While Top Ten and Promethea are extraordinary in their own right, Moore has done the impossible with Tom Strong; he's built a deep, rich history and an epic legacy in less than 15 issues. Every time it comes out I'm reminded why I love it as much as I do, it's one of the few reasons I'm still reading comic books.
