Having read the entire book series it’s mostly faithful to the beginning of the story…. There are some differences… mainly the arc with Beth. The story starts pretty slow in the books so for it to be the same in the show is normal. Yorick is pretty true to his literary counter part, and him being a self centered jerk is part of it. There are a lot of characters and plot arcs, and hopefully they will all get properly adapted with the humor intact. It’s a bit self serious at first but again that’s how it starts out.
