One of the things that made the John Wick movies so interesting was the idea of an intricate and organized underworld that existed just under the surface that went apparently unnoticed by those that weren’t part of it.
Clearly, that world is full of interesting characters and stories so setting a new story in that world could certainly work.
Apparently, the reason Lionsgate was interested in the script, they beat out Universal and Warner Bros. who were both also interested, was specifically because they saw in it potential to grow the John Wick franchise.
As ideas go, this isn’t the worst one we’ve heard.
