I quite enjoyed it. I enjoyed the prospect of an even more messed up mirror image of Frank - similar origin, similar skills, similar backround, similar motivations - but this guy makes Frank look positively balanced and sane by comparison.
Sadly, I expect that rather than introduce a new nemesis for Frank, this story will see Johnny dead by the end of it - probably at the hands of Frank himself when he realises that the guy is too unhinged.
Nice seeing Tex back on art aswell.
The preview for ish 2 is implying the guy is amnesiac, schizoid, and possibly super powered......hope Frank has some bullets ready for this guy.
