I do not understand this films greatness

Rating: 3/10 (1 January 2016)

I'd saved this for a special day when I wanted quality. Shame. Completely bizarre and unrealistic story. So contrived and stupid. It wasn't remotely believable. Just silly. The point of the entire frame was to get Matt Damon and Robin Williams in the same room. They could've saved so much time shortening it. The rest was just transport. Everything about the kids life was uninteresting. The silliest sob story. His relationship with the Harvard girl was a yawn-fest. Bad acting.
I'm a liberal, so they were preaching to the choir, but even I found the long liberal speeches a bore. People don't talk like that. There's a rule in fiction... show don't tell. They forgot that rule. How did this film get nominated for nine Oscars, including best picture?!? This is first year English major level of writing. So bad dialogue. Such a weak contrived script. It tries to make some blindingly obvious points about it sucking to be poor. This is not news. Also... everybody was hot and sexy with a smoking hot body. Not believable at all. Just took me right out of it.
Both me and my girlfriend sat with dropped jaws wondering how this got so high ratings. The good acting does not save this film. Yes, there's some top notch fine acting here. Both Matt Damon and Robin Williams to stellar performances. Stellan Skarsgård, who I know is a good actor, couldn't save his silly role. Such a stupid idea for a film.
