Anything that gets in the way of gameplay needs to be adjusted. Really, a movie-like story is a completely wrong direction for a game, since a movie is meant as a passive activity and a game as an active one. Games need the ability to change the outcome of the story, not to live through a predetermined story and maybe beating up baddies in between to qualify it as a game. Sure, you might love the feeling of just living through a story, but you could just as well read a book then (cheaper, easier available, more socially acceptable and usually higher quality).
Eternal Darkness didn't have great gameplay. Hell, it had flaws like "you can't combo when there's a wall next to you", which are absolutely idiotic! The game relied on its story to stay alive and make it seem like more than a straight-forward hack&slay. Hell, FFCC, which is often criticized for lack of gameplay depth, had deeper gameplay than ED! Only MMORPGs are worse in that respect.
