Back in the day it was revolutionary and important I guess, but by nowadays standards it's utterly mediocre movie despite people praising it as something amazing, but to be fair I don't think I'd find movie from CK era which I'd like while I have no problem to find better artists from Beatles era whose music I enjoy much more and like them even nowadays compared to present day music.

And one more unpopular opinion from someone who experienced jail like environment I think even recent highly rated Shawshank redemption while very good and enjoyable movie is romantic unrealistic fairy tale (for women) and I'd rather recommend everyone to watch Das Experiment to see more realistic display of prison I can sign, yet I've of them is rated asking best movies in history and the other is pretty much unknown.
