Quoteeh.... ?.......huh.........?...? Why...?
As I said, because the alien in that movie doesn't fight, or take any real attack. It's speed is not represented well (except for the scene wit Dallas), only it's strenght. That's the only thing you can rely on. Every other aspects must be assumptions, which cannot be reliable in your case, when you state the pred would kill an alien easily imo. That's why you need at least Aliens I think.
No, your posts weren't bouncers. I see what you're telling, but I think you should put more effort to it before stating such a radical statement. That's all, and it's only what I think. An opinion. You don't need to self destruct.
