I can't imagine the pain and then the joy one would have gone through by betting on Moonlight and having La La Land being announced as the winner at first. The odds were terrible though for La La Land.
They hype La la Land so much that's why bettors think it is an easy money, I don't know if there is a monopoly that happens but base on my observation when a certain bet is a heavy favorites, it would not usually win. This does not apply in Oscars alone as the same scenario happened many times in sports and in politics. Maybe we should have to bet against the public all the time and stop analyzing bets.
of course it is because the experts are totally incompetent or they just have an agenda and outright lie.
I doubt they manipulate the results because of the bets, because the market is insignificant compared to sport betting and there are bigger interests than money
better make your own analysis and ignore the experts and the media
its really an expected that la la land lose but there's always a reason behind and we know that aside from many categories there's also
some impact with betting with the public so they gave small odd for la la land, for the public to feel that there's some edge for this film
just like with the presidency providing small odd for clinton and the results went for trump.
