It's a long series, but maaaan it's such a fun ride. The characters grow up in real time (more or less), they mature, grow and develop over the years. Character arcs span over the course of years, we see their struggles, their successes, their relationships, their ups, their downs, gaining and losing friends, questioning their actions. It's so great. Growing up side by side Finn and seeing him grow into the thoughtful and courageous young man he is today was such a great experience.
