A Separate Peace comparison

The movie started in a flashback to the fake trial. The boys were all playing a game after Gene found his room. Finny came up with all the rules in both the book and the movie. Leper came up with the name of Blitzball in the movie, but in the book Finny did.

Gene said that he didnt have another roommate and didnt go out for sports. This happened in both. Leper went and picked apples in the book and the movie. Finny also trained Gene for the winter Olympics. Finny did this in both the move and the book. I feel all these changes stayed the same because they were important key facts. Yes I agree with the choices of leaving these the same.
