It has to be said, Goodfellas won the test of time presently, no doubt
even if you think dances is the better movie, there's no denying that goodfellas is seen as the better film today and that it was snubbed at the oscars. again,that could change in 50 years, but right now, it's delusional to think otherwise.
Like for instance, on parks and recreation, one of the guys is made fun of for liking dances with wolves because it's seen as LAME. absolutely no one thinks that of goodfellas and if you do you're making fun of yourself more than anyone could, truthfully.
as i said before, things change and predicting the canon of classic cinema decades down the line is harder than it looks, so i'm not even saying that dances with wolves won't be rediscovered as a great and goodfellas won't be seen as relatively mediocre (but i'm also not saying that) however the people here saying dances with wolves is seen as the superior movie nowadays, you really need a reality check...
I know that I shall meet my fate, somewhere among the clouds above
