So why are there New Kids on the Block comics? Because these guys were ridiculously popular. They were trendsetters who basically defined what the 1990s, or at least the early 1990s, was going to become. It's hard to understand now, because they're little more than a punchline to jokes about the era -- but people really BELIEVED in this stuff back in 1991. And I mean 'believed' as literally as possible.
But we'll get to that in due time.
