[Actually 2.5 stars. Like it makes any differences in the future of humanity!] 
 [?]Likes: 
 * Easy to read 
 * Atmosphere (I liked it at first, mysterious and frightening. It was like that for about half of the book.) 
 * Glader's Language (I liked it that the author had used weird words instead of real swears. Shuck, shank, klunk, good that!) 
 [?]Dislikes: 
 * Thomas (He was the dumbest kid! His stupid questions filled 46% of the book. And then he had weird emotions that I couldn't empathy with) 
 * Storyline (I liked how the story started. I'd even give 4 stars to the first 2/3 of it. But the back story sucked! And it was the heart of the plot, so I had no choice but to give it 2.5 stars) 
 * Reactions and Dialogs (at first everyone was secretive and confusing for no reason. And they did odd things that I thought it's a creepy dream. And the dialogs were unnatural) 
 * Unexplained Mysteries (what I said about the atmosphere, that odd things happened like it's a total artificial or virtual world, but then everything turned out to be happening in the real world. So the mysteries remained unexplained. like, how did they control some people? how was the walls movies against physics? what was the cliff? and so on. 
 P.S. I couldn't stop feeling that I'm reading a story on wattpad! 
 P.S.2. I won't read the next book, even though this book was ended with "The end of the book ONE. Read the next book or else, you piece of klunk!" 
 P.S.3. it was the first time that I read the book before I watched the movie, and it was an amazing experience! having said that, I can't deny that I liked the movie more. cause every unexplained mystery was removed and everything was logical. it was like some grown up guy had rewritten a preteen's essay!
