Watched the Fifty shades Freed today

I watched the Fifty Shades Freed today with my friends. I love the ending of this movie. It shows how Love can change anything even a heart of a manipulating and controlling man. I've watched all 3 movies; Fifty Shades of Gray, Fifth Shades Darker, and the Fifty Shades Freed. Love them all but I was told the book is a lot better. I probably won't know the difference because I'm likely not going to read the book.
