I don't see how anyone can argue this was a murder mystery story.
If it hadn't been leaked in advance, would ANYONE have picked Wally as the murderer??
Where were the breadcrumbs?
Where was the hint that Wally West would act like a psychotic super villian and somehow manipulate everything via time travel?
Which, was JUST explained in the Flash books as NO LONGER POSSIBLE for speedsters.
This book is a mess - with more logic leaps and plot holes than Identity Crisis ever had.
If you found this book an enjoyable read, more power to you - I found it to be, probably the worst thing I've ever read from DC.
