If it's exactly as it was in the films, I'll have no problem with it. I just don't want a silent Jason to start grunting. (Part 6, for example)
Sometimes, just because you never heard someone make a noise in a movie doesn't mean that they can't make a noise at all.
The killer in part 5 was human, not jason.. and human's make noises just as much as Jason from other parts make noises.
It's like Mr. Bean, never really talked in his earlier skits.. but he's human. We KNOW he can talk, but he chooses to mumble, because it keeps a sorta veil of mystery to him. And then of course he later starts talking a little more in later episodes.
