I said we WANT. Not we GET. Of course we want the film to be as close to the book as it is. Except maybe for the couple of mistakes Tolkien himself made in the editing of his timelines, etc. (Sorry, just being picky with the Bard)
So let's scrap the entire scene and have Sam wake up and meet Gandalf with Frodo already awake. As it's this in the books, then let's have that. But do you really think we the readers can dictate what will be on a Movie adaptation just becasue it's not exactly like it is in the books? So therefore, let's not have a reunion scene with the main characters. For the uninitiated, non book reader (which I put it to you were the VAST majority of people going to see this movie, first time at least!), NOT to have a 'happy ending(s)' like this with the characters celebrating together would be silly.
