@filmfann I wish to agree and disagree with your list.
When viewed through the context of the era in which it was made I consider D, W. Griffiths’ The Birth Of a Nation to be one of the greatest movies ever made. Consider: it was released in 1915, when the art of movie making was barely a decade old, yet it skillfully employs several very modern film editing techniques to enhance the viewing experience. Plus it explores a side of the Civil War largely ignored by other movies, namely the effect on a family when the males of the family end up fighting for both the Union and the Confederacy.
As to A Clockwork Orange, I somehow wasn’t aware that it was that highly rated when it came out. I have seen it and, I agree, it is an acquired taste.
Finally, in my opinion, The Deer Hunter is the most over hyped and overrated movie of all time. Insipid does not begin to describe my impression of it (and I have actually seen it more than once through the years.) That it scored the Best Picture Oscar over the far deeper & better Apocalypse Now still rankles me a little bit.
Another movie I consider to be way overrated is The Shawshank Redemption. Yes, it is a good movie, but is it as great as people think it is? I’m not convinced.
