Me, I liked how there was constantly action and the story was 更多 at a fast pace then the 秒 part. In the 秒 part it was just kinda like here go do this and they don't get caught 或者 into as many fights. Plus, it wasn't as depresing as the 秒 part.
I like the first few 图书 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, 你 know? I felt like the first 图书 had less of that.
