The first pages of the issue are good.. Batman solving the puzzles and trying to get to the riddler as fast as possible is just amazing, I think the plot goes from more to less when Batman leaves the riddle as "silly", this "plot twist" is very bland and cheap, and the sudden change of personality and goals of the riddle feels unnatural and rushed.. However, the last page of the comic poses an unexpected (Excellent, by the way) plot twist  and turns the zero interest I had in the outcome into an impatience and excitement to see the end of this arc.
