Glad you liked it!
In a way it kind of is an origin story for Hugo Strange – it’s an adaptation of his first Golden Age stories back in 1940. If you’re curious, Wagner attempted to connect it to the Post-Crisis origin of Hugo Strange, “Prey,” which we actually covered all the way back in the very beginnings of the club!
And there actually is a sequel to this mini-series that does continue a lot of this called “Batman & The Mad Monk,” but sadly it’s not digitalized and therefore not on DCUI. 
Thanks for sharing your thoughts!
