4/5 or 4.5/5, haven't made up my mind yet.
An easy read, helped by the fact that the chapters are only a few pages long. The history intertwined with the loveable fictional characters aids this further.
I feel like this book was written as a screenplay. I had absolutely no issue imagining this story being turned into a film. Several parts made me think of 'Big Fish', 'Water for Elephants' and 'The Greatest Showman'.
So if you liked these films, I guess this might be the book for you.
