A most enjoyable colorful comedy/thriller/crime/drama

Rating: 8/10 (17 February 2020)

I liked Parasite very much and had predicted that it would win the Oscar for best foreign language film - as it rightfully did !
However, I could never have imagined that Parasite would also win in the best picture category as well. Shouldn't the Academy's eligibility rules permit a film to enter in only ONE of these two categories ? ? ?
