Videos/posts like this won't change the minds of those hating on the film. The people who didn't like the movie are in the minority. Numbers and reviews from credible crisitcs don'tlie. The film has done well both critically and at the box office.
I say, don't waste your time arguing with those trash talking the movie and just be content with the fact that this movie was made and that you enjoy it. Gareth Edwards nailed it in my opinion, and I couldn't care less if some people didn't like it. I liked it and that's all that matters to me.
