Here we finally get an expansion of the League with three new characters ... and what does it say when the best issues of Johns' rebooted League are the ones that don't star the big guns? But here it's definitely the relationship between Elemental Woman, Firestorm,and the new Atom that shines. And the return of a classic victim. So the Grid definitely earns a "good" rating. 
 PS: Is it just me or does Johns' JL Flash read more like Wally West than Barry Allen? 
 Unfortunately the volume ends with two incomprehensible parts of the 6-part Trinity War saga. Why does DC hate us readers so much that they keep putting out these horrible trades that are either fragmentary or largely duplicate each other? They used to know how to lay out trades before the New 52. In any case, I've skipped the Trinity War until I gets its own complete trade and thanked the library system that I didn't actually pay $24.99 for three issues. This review is nonetheless based solely on those three issues of The Grid;if I'd averaged in the horrible Trinity War crossover, the rating would have dropped to a 3/5..
