Me, I liked how there was constantly action and the story was еще at a fast pace then the секунда part. In the секунда part it was just kinda like here go do this and they don't get caught или into as many fights. Plus, it wasn't as depresing as the секунда part.
I like the first few Книги the best (1-4), after that, it just starts to lose a bit of purpose. Like not everything is going somewhere, I feel like JP is stalling for time because nothing really went anywhere after that. There will be build up to an event, then the event will happen, then it will end, and that will be it. It doesn't go anywhere, Ты know? I felt like the first Книги had less of that.
I dont think I particularly like one part over the other. I hated Schools out forever and FANG. But my Favourite ones are MAX and the Энджел Experiment.
