Ridiculously bold statement that buddy. Yes there were many, many bad films made in that decade, the majority of which had a certain US cheesy sheen on them but it's a decade filled with great films....
Fight Club, The Matrix, Saving Private Ryan, 12 Monkeys, Jackie Brown....like fucking loads
Not sure the ratio of bad/terrible is any worse than any other decade. It would be easy to argue the percentage of shite films being released is far worse now....
Shawshank Redemption is arguably the greatest, if not certainly top 3, ever made. Schindler's List. Forest Gump. Silence of the Lambs. Unforgiven, Dances with Wolves, Goodfellas (one of my all time favs), Fargo, Green Mile, Good Will Hunting (another fav), Terminator 2, Big Lebowski, Toy Story, Lion King, Usual Suspects, Train Spotting, La Confidential, American Beauty, Home Alone, Boyz in the Hood, Truman Show, Casino, Mrs Doubtfire, Point Break.
Probably my favourite era of films, truth be told. There are likely plenty more, that is just what is saved on my external hard drive.
