A book is like a lake – you can paddle about, stop, go back a bit, plumb the depths, admire the scenery, take as long as you want. TV is a river – and a fast ﬂowing one at that – miss something and it’s gone. There’s no going back. So what works in a book doesn’t necessarily work in a TV series. This is why Animalia the TV series is so different from Animalia the book.
