The reason for that is because Hollywood will do whatever to movies based on games to bring in more sales and money, and unfortunately they tend to feel that the original story lines and whatnot will not be good for whatever reason. If they disgruntle the core fans of the games/whatever, they won't care because that base is so small, and if they're appeasing the masses then they'll care even less.
The biggest reason why I feel that Halo might not be a part of that group is simply because of how big it's become. If Hollywood decides to screw everything up, they'll of course upset the core fans, but this base of core fans will be very large in numbers relative to ones past, and because of that a larger portion of the audience. I hope with that being said this movie stays as close to the game as possible.
