You hit a nerve! I have just read both books also. I agree that while reading "Night School" by Lee Child, I had the thought that while a very enjoyable read, Jack Reacher was still as one dimensional as ever. He was going to stomp aground stirring up a commotion, have a big fight scene (which IMHO was contrived as any that Child has concocted) and then by superior reasoning power and sheer force of presence was going to solve the mystery. After the previous Reacher novel, I resolved to quit reading the series. Having the premise that Reacher was back in the Army sucked me back in. Again, I read the novel and enjoyed reading it. Am I ever going to buy a new novel featuring Reacher and written by Lee Child? I don't think so. .....
Now, Michael Connelly's character development of Harry Bosch just keeps getting better. I very much enjoyed "The Wrong Side of Goodbye" and the continued very likable character of Harry Bosch. He reminds me of an old LV Metro Detective that I knew. I can count on Harry always muddling thru any adversity and wrinkle following the clues that are presented to him. I like the disdain Harry feels toward incompetent superiors in the PD's hierarchy. I will continue reading anything that Michael Connelly writes, no matter which series in which it is the next book. ......
