Seriously, a remake wouldn't be bad. I'd like to see them expound on the whole Jockey thing. Maybe not give the origins, but show the ship crash and a space jockey's chest being tore open. Nothing revealing, but just giving a little bit more to the picture.
The only thing I see wrong is that if they made one, Weaver wouldn't be in it, so the whole line of movies would be screwed up. Big problem.
