This movie is really good. Of course there were some deleted scenes that did not make it in the final cut, as well as the movie feeling too short, but it really delivered. While Peele only produced this movie, I think it was still very entertaining.
I think the story is very easy to grasp and the deeper meaning is evident so I do not know why people are giving the movie low ratings. The trailers still did a good job concealing some minor surprises in the plot so I won't give them away.
Overall this movie deserves better ratings because there is nothing absolutely wrong with it.
