To me, the guy doesn't sound bitter; just someone who's managed to weather a lot of what the film industry threw at just about every writer, through those decades. It's an interesting read, for historical value. Very insightful. I don't know where his concept of Aliens becomnig Predators would have got the 'versus' theme from, though, as that would make them one and the same thing. I wouldn't agree with somehting like that being put on screen, but then, there's only a hint of it in that interview. The same which has been in others. I would need to know a lot more about it, before just condemning it, out of hand..
