In terms of communicating and developing the themes, no, not really. It's different t front he book, because it's a different story inspired by, not an adaptation. The important thing is hitting the Tolkienian notes and personal themes. And even more the details that would matter to reinforce those are things like different registers for characters (Galadriel is walking around talking like the Book of Common Prayer, while the Harfoots are earthy and simple), or people singing songs for their friends. Not calander dates.
