Films I want to watch from Hollywood's golden era.

/u/StopReadinMyUsername on reddit created a list called "1001 'GREATEST' MOVIES OF ALL TIME" in 2015.

Since this list is still very popular, he posted an updated list on reddit in April 2020.

For this list he combined the average scores from IMDb, Letterboxd, Rotten Tomatoes & Metacritic, and tweaked the results with data from Letterboxd, iCheckMovies, TSPDT?, TMDb and IMDb.

The top 300 best silent era films are based on the votes on the silentera.com website. The list is not limited to features exclusively. True silent films (like City Lights) not made in the default silent cinema timeline (1891-1929) are also accepted. Films receiving votes must still exist somewhere and in some viewable form. We limit the list to films that were produced to be silent films exclusively (synchronized music tracks are acceptable, but part-talkies and talkies that have only survived as silents are out).

Horror is one of the most readily dismissed genres from critics and film buffs, yet is, arguably, the genre with the most avid and steadfast niche following and remains popular with the general public. With horror films aiming to terrify, spook, shock, disturb, repulse, amuse, entertain and more, it's no wonder the genre is so varied, divisive and controversial.

With so many people ignoring or simply not understanding horror, many great films slip under the radar and are relatively unknown to an audience outside of hardcore horror fans. In order to counteract this and bring awareness to the greatness of the genre, this list was created.

Compiled using 2,614 lists taken from various critics/polls/magazines/books/websites/forums/horror fans, They Shoot Zombies, Don't They? is intended to be the ultimate canonical top 1000 horror list. Spanning several decades, countries and sub-genres, and using lists from a wide range of people and publications, the resulting list is quite a diverse spread and representation of the best of horror.

From Universal monsters to modern serial killers, creature features to slasher flicks — these are the films that keep us forever screaming in the dark.

Of course you do! Freaking out with your fellow audience member when something shocking happens, or jolting together as one during a primo jump scare, is one of the great pleasures of going to the movies. And over the past 100-plus years, the art form has figured out almost every possible way to frighten us, unnerve us, make our hair stand on us, chill us, thrill us and touch upon our most primal of fears. Then, just when you think it’s safe to go back to the theater, something else comes along that reminds us that there are always new ways to come us screaming in the dark. If you can count on the movies for anything, it’s that there seems to be an exhaustible supply of scares.

Naturally, everyone who helped cobble together the 101 best horror films of all time like scary movies. A lot. So we’ve gathered all of the old-school monster movies and modern serial-killer thrillers, the creature features and the slasher flicks, the canon-worthy creepfests from Universal and Hammer and A24, and come up this definitive list (or our definitive list, at least) of the greatest the genre has to offer. Just remember, as you read this list: It’s only a movie. Say that 101 times in a row, and you may just it make through this list…alive!
