This movie is funny, suspenseful, and engaging from the start. It's one of those movies that I believe anyone could truly enjoy– Hollywood blockbuster types, arthouse folks, film snobs, etc. An excellent story can be digested by anyone.
I think what makes Parasite (2019) exceptional is that it has all the elements that make a movie not only entertaining but good enough to make you think. The setup is fun and exciting, but at some point in the story, the reality of the movie's focus – economic inequality – really sets in.
I definitely recommend it, if literally everyone you know who has seen it hasn't already.
