I have yet to watch the trailer or really know anything of the plot, but let me just say, based on what I do know, the concept is ridiculously horrible. Everyone says that Hollywood (i.e. the film industry) is running out of ideas, but I think that the real problem is that they not only have run out of original and decent ideas (first Pixels, now this), but don't even bother to even try to come up with new ones.
I am all for the downvote campaign, but I believe this movie is part of a larger problem in American entertainment and culture. This larger problem, as I percieve it, is mainly consistent by sticking with the same old tropes, marketing strategies, cast members, etc. (Let me know if you wish me to elaborate.)
As I see it, this stale establishment, as I will refer to it in this post, will go on if we only tackle it movie by movie, as it it were an individual problem for each movie. I think it is our right and duty, as the people, to stand up and fight against this stale establishment, albeit peacefully. If there is hope for change, whether it be in entertainment, broader culture, politics, or some other field, the masses should work together to bring the change about. I don't think a downvote campaign will be enough to bring about this change alone, but it is a good start.
