I watched these movies back to back starting with 12 years a slave.
After watching both films The Butler to me was so much more better in every way.; Story, cinematography, acting, etc...
12 Years a slave seemed a little tedious and didnt emote well for me. I kinda watched it and felt nothing.
The Butler had so much more to offer IMO there were High points, low points, times of hope, and despair.
I believe 12 Years is over hyped and lacks some story telling to really get the viewer into the story. That my opinion what about ya'll?
