Here's a link to an article today at Forbes as to why some don't think this movie's premise is good.
Mileage varies and many will, of course, disagree with the article. I agreed with it because it expressed how I felt much more articulately than I was able. Its author might be considered a "mainstream" film goer. His name is Scott Mendelson. Some will agree; some will vehemently disagree, but it's good food for thought.
