Are you trying to say that Predator is less scary than Alien?
I didn't make the chart, but yes.
I'm not sure how anyone can see the Predators as "scary" honestly. They're hunters that only taget prey who can fight back. Most of the fear that comes from horror films is the fact that you get the feeling the killer would kill practically anyone regardless of who they are, you can't get the same feeling with creatures that have a code like the Predator.
