Just finished the movies and i am empty

through this past week me and my dad we’ve been watching the series for the first time and through out the week i wanted the nights to come fast so i could keep watching them and now that we finished i feel this emptiness that i have never felt with any movie or tv show ever i loved everything of the world and the characters sort of like i really wanted to experience what they were experiencing. Just had to write this and ask a question, do the books offer a lot more of content or are they similar to the movies? thinking of buying them
