I love all of the books, and I read them every few years just for the experience.
The movies depart from the books in many ways. Plot elements that were crucial in the books were dropped in the movies. (For example, the fact that Bilbo had cursed Gollum that if he ever touched the ring again, he would die, and it was that curse that actually enabled the destruction of the ring was completely omitted from the movies.) Despite the differences, despite the fact that a lot of LOTR material was placed into the Hobbit movie--I still enjoy the movies. They will never have the impact that the books have on me.
Bilbo cursed Gollum? I don’t remember that.
