"Hidden Figures" was okay, but like @smurfy it seems like the most "commercial" of all the pictures in this field. I was really looking forward to this and was a bit let down, because I just felt the script wasn't up to snuff. And while I thought she was good, I was a bit surprised that Octavia Spencer got the Oscar nod of the three ladies. She's great (as always) but it's definitely the least showy part of the three major characters in the movie.
I do think that it was a commercial movie and not particularly creative other than the subject matter. But, it was different because it explored a kind of story that isn't usually explored. And I think it's important to explore it. (My first-grader niece, who always has liked dinosaurs, told my sister the other day that she can't be a paleontologist; some boys at school had told her that dinosaurs are only for boys. My niece has an aptitude for math and, even today, I think she'll still be led to believe that math is not the right path for her. I loved that, when I went to see the movie, there was a little boy with a NASA cap watching the movie. I hope that now little girls will start wearing NASA caps.)
Yes, Octavia was the least "showy" of the three characters, but she seemed more authentic because of that. I don't think that an African-American woman working for NASA back then could be very showy.
