Fans are not kind to movies they care about that don't make the right moves. People who work on those movies don't enjoy the criticism. I think they perceive criticism as toxicity, whether it actually is or not. For the most part, a lot of the recent entries (and even the older entries) in my favorite series have made a lot of wrong moves. I hoped The Predator would be good, but I expected it to be bad. And it is. Too bad, but the silliness about the endings is just icing on the cake.
I think the Alien and the Predator both have the same problem: The directors charged with their care don't seem to know what to do with them (or no longer want to do anything with them). So the title creatures live better in our memories and sometimes the EU. That extends to Star Wars universe, too. THe new movies can't seem to approach (let alone rise above) the standards set by the two oldest movies. Does that also sound familiar? 'Cause I'd say Alien and Predator series have the same problems.
