This is the second time I've read this. I loved it the first time around, so I figured I'd revisit to see anything I might have missed the first time around. 
 I love both Grant Morrison and Sean Murphy, so it's really a no brainer that I'd return to this book. 
 The concept of flipping between two words isn't a new one, but Morrison puts his unique spin on the concept, and combined with Murphy's art it really brings a new light to the idea. 
 Joe and Chakk are such likeable characters in their own ways. Joe is completely relatable as the outsider artistic nerd, while Chakk as a giant warrior rat is the perfect, grumpy protector. 
 Joe shifting in out and of the real world and the imaginary added a nice depth, so you could see exactly where he was in his struggle within the house. I love that Sean Murphy insisted on drawing a complete floorplan of the house, easily allowing the reader to visualise where Joe was at both within his house and within the world he's visited. 
 I still love the ending, and it's one of those stories that I hope one day makes it to the big screen.
