I was disappointed in "Miss Peregrine's Home for Peculiar Children". It had so much potential and it failed miserably. Therefore I had not initially planned to read on in the series, but as the sequel kept enticing me with its deliciously dark cover and I kept hearing it praised everywhere, I decided to read it anyway. After all, it is Halloween and the season is suitable for a little bit of peculiarity. 
 But reading on in the series turned out to be a dreadful mistake. "Hollow City" doesn't improve the series. In fact, it only makes it worse. 
 There's no unity between Riggs' words and pictures. The setup of everything is so stiff and stilted. The plot is lacking, the characters have no interesting traits besides their peculiarities or supernormal powers. Riggs' never bothers to characterize them, thinking that their extraordinary powers are enough. As a result the characters are one-dimensional. So endlessly flat. 
 And the plot? A wild-goose chase. Almost literally. 
 I don't know why I even bothered.
