I’m sure this is an unpopular opinion here but -

Shawshank is not typically amongst top 100 lists. It does well on audience polls, but isn’t super highly respected in the film world. It’s a fine, simple film with little complexity. It pioneered no new techniques either technically, narratively, or in performance. Had it not run forever on TNT or whatever it would largely be forgotten.

IMHO it’s the most overrated film of all time. Not to say it’s bad, it’s great comfort food. But top 100 of all time? Nah. Not even top 10 in 1994. I’d rank Pulp Fiction, The Crow, Clerks, Leon, The Lion King, Legend of the Drunken Master, Chungking Express, Satantango, Red, White, Shallow Grave, etc above it.
