Okay, The Maze Runner was awesome. I liked Thomas and I liked most of the characters. The writing was not very good, but I can bear with that. The Scorch Trials was not that good, but I went on with the series because I needed answers to A LOT of questions. But The Death Cure was just awful. Not only because of the writing, which was more tedious than in TST, but also because I hated Thomas passionately. He was really annoying throughout the whole book, not to mention that the book only focused on him. Minho could've been inexistent, it wouldn't have changed the plot. 
 Also, why did Thomas act as a heartless egotistic bastard? He didn't want his memories back, even though he could've saved millions of people by simply getting them back. But, no, WICKED is bad and all that blah blah blah. Excuse me, Thomas, but (view spoiler)[Newt, your best friend, had the Flare (hide spoiler)]. Wouldn't that motivate you to, ya know, find a cure. 
 Too many questions remained unanswered even after the final novel in the Maze Runner trilogy. Why did Thomas remember Teresa so well? Why did WICKED basically re-create The Hunger Games by building the maze? (view spoiler)[I know, they needed information from the Immunes' brains so they could study their behavior, but the immunity was in their DNA, not in their brain. (hide spoiler)] 
 The end was disappointing, probably the most disappointing thing I've ever read. Thomas, being again extremely selfish, (view spoiler)[leaves everybody on Earth to die by gathering his immune 'friends' in a place with grass and rainbows that appeared out of nowhere. He knows that the process of Earth being Flare-less again was going to be painful and ugly, but he doesn't care. As long as His Majesty Thomas is okay, the world can go fuck itself (hide spoiler)]. 
 A lot of other things disappointed me, for example (view spoiler)[Teresa's death, which was plain, badly written, and had no heroism. The only scene that made me cry was Newt's death (hide spoiler)]. I'm still not over that. So, basically, I shouldn't have continued the series. I should have stuck with reading just the first book.
