That always drove me nuts about "The Godfather". Why didn't they have, say, a hit man having dinner at the restaurant, and have him do the killing? Why the Don's son? He would never have been chosen to do it in real life. Picking him made no sense to me and took away alot of the believability of the movie. There were other ways to kill them at the restaurant. It wasn't the only thing that bothers me, but it is the biggest thing.
