Movie VS Book the Time Machiene

the movie of the time machine(2002) and the book itself is very similar in terms of the general idea and characters. the different versions also contains the divided human species. the movie however, changes the character motivation of the plot completely. the time traveler in the movie goes to the future to determine why he cannot change the past, while in the book the time traveler went into the future to simply explore the future. the eloi in the movie are not as graceful and childlike s described in the book. the movie also added a single villian in the movie, while the book does not. in the end, the time traveler stayed in the future in the movie, while in the book, he goes back and explore, then disappeared. A funny point about the movie si that the book is actually mentioned in the story,and the general plot which is lated conducted. i do not know if that was a mistake since it left us confused.
