What's so awful about movies based on something else? Some of my favorite films are adaptations of novels or TV shows, and video game adaptations are improving dramatically--the problem is the lack of serious regard for video games to begin with, not the process of transitioning them to film. I've enjoyed a lot of sequels and remakes, too.
Why would I turn up my nose at a film with a plot, special effects, actors, and setting reminiscent of one that I already know that I enjoy?
Everybody complains about originality and "Hollywood crap" whenever a sequel comes out that they don't like, particularly if it's a franchise that they don't care for. When it's something they're interested in, you won't hear that. The fact that billions of dollars are still being made on Hollywood films proves that people take no issue with the fare coming out of the film industry to this day--they simply hate seeing sequels to, or remakes of, films that they personally didn't care for to begin with.
Putting down the people who *do* like them is crude and unnecessary.
