4,5/5. As much as I like the Batman Flash team crossover, one of the rare crossover I enjoy, this one just seem to get out of nowhere in the Batman time line... Anyway, the issue itself is good and will be part of a 4 issues mini-series, two on Batman part and two on Flash I assume. Good mysteries, cool illustrations and lot of action. Its a very good comic, just kind of caught me off guard a little.
