Know one of the three preceding Gegan which Inferno parts is imperative as it is here at the completion of the series.
Spoilers I do not really, but it should be noted at this point that everything turns (as almost always) for good.
A little bit I'm still disappointed. Somehow missing here the "thrill" to the end. A thrilling end I imagine otherwise. For example, the second part of the whole story was more exciting than the Joker finds the Batcave. The end of Enfer and Joker not berrauscht really. And the matching acquittal for Batman remains off. The finish is not bad, but it could have something ... how should I say ... may be more.
For this reason, I am afraid to pull off a star. The remaining four still remain, however, since the implementation has been re-implemented once known Sychronsprechern clean.
