You shouldn't really take stock in the Academy Awards. Lots of political reasonings go into it such as equality, 'diversity for diversity's sake', anti-right crap, all the makings of left-leaning folk especially in the state most known for left-leaning.
I've seen some Best Picture winners that were really good movies that are praised to this day, some really good movies that are sadly forgotten about and some boring/shit movie that was preachy, up its own ass, obvious low hanging fruit to appease Academy people's agenda etc.
Shakespeare in Love was deemed a better movie than Saving Private Ryan one year... that's all you need to know when watching these award ceremonies.
