Since this is the last volume of Chew, let me give you my overall impression about the series, followed by a short review of volume 12. 
 Chew and Brian Vaughan's Saga are the reasons why I started reading Image Comics titles. 
 Chew, written by John Layman and drawn by Rob Guillory is a unique story about people having food-related superpowers, a mysterious space writing and a chronicle of events that centers in family and friendship - all drenched in edible barf, blood, fingers, ear lobes and whatever crazy rotten stuff Layman can throw to our epicurean taste buds. It is all original from start to finish. Guillory's cartoonish style of drawing perfectly complements the rowdiness and frenetic action Chew offers to its readers. 
 This, together with Brian Vaughan's Saga are the reasons why I started reading Image Comics titles. The series has been consistently entertaining and violent in a way which is very palatable and delicious to my taste, even though much of it are really guilty pleasures. 
 I highly recommend Chew to everybody. 
 And as for the final volume, it didn't really meet my expectations, given that it had been set low from that very disappointing volume 11. The last volume felt very different from what Chew is all about: a fast-paced fun and non-depressing story. Yet volume 12 is a bit dragging at many times, all thanks to Savoy's pompous conversations and also quite depressing in its ending. 
 The ending was also unexpected in a bad way. Note that there are surprises in stories which are genuinely good. Chew's ending is not. 
 So even though I find the whole Chew series to be consistently fun and engaging, its last two volumes lack the spirit that Chew has and ended in a rather mediocre way. Still, congratulations to John Layman and Rob Guillory for the whole reading experience.
