It seems people only see what they want to see. It was a well-directed, well acted movie regardless of what you think about the social commentary in the film. Although honestly, I don't think there was much social commentary. Peele was using racially charged socially awkwardness (something that you should know happens in real life unless you live under a rock) to both hide what the antagonists were up to and to create tension. I thought that was brilliantly done and definitely different from most horror movies. It definitely wasn't "literally the same" as every other slasher movies. The racial stuff was really just a plot device, and not the center of the movie.
I wouldn't say it was my favorite film because thrillers and horror movies aren't usually my thing, although one of my favorite movies is a slasher flick. Some people have overrated it but you are certainly underrating this film.
