As you may or may not know by now, I'm a huge fan of PS238, the series that deals with a secret school for the superhuman children. This series could easily have been very "kiddy" or at worst, derivative and weak. But, it is a testament to Aaron Williams' talent that he can make the children complex and fully developed as characters while still allowing them to be, well, children.
That's not to say that it's all about the kids. In what can truly be called an ensemble cast, the story (and many, many) mysteries of PS238 revolve around the staff. Again, Williams is clearly creating an epic in his own right; there are layers and layers of mysteries in the first 12 issues alone than in the entire annual output of Marvel or DC. All of this is to draw in the readers, and the appeal is to humor that is aimed as much at the kids as at the adults. As a side note, I've spent most of my life in and around people who work in education, so let me say that they would appreciate the attempts at "teacher humor" that are on display in this series;
And really, it's all about a lot of great storytelling, with suspense, humor and intelligent plotting. Great characters who at once embody the archtypes they portray while casting them in new directions. Do yourself a favor: jump over to the website and buy some, right now. Or at the very least, check out the early issues of the series, put up as a webcomic.
