I must admit that I have a few problems with the IMDb list, some I would argue are not great films at all (Wizard of Oz, Braveheart, Jurassic Park) but many are mis-ranked and there are (IMO obviously) several ommisions
No mention of Bladerunner for instance, nor the Matrix, nor Metropolis, nor Grand Budapest, Resevoir dogs, Amelie, Léon, Toy Story, The Italian Job, The Terminator, Blue Velvet, L.A. Confidential, Trainspotting, Three Colours trilogy, A Matter of Life and Death, The Shining, Heat, Alien or The Dark Knight all of which (and probably others I can’t recall just at the moment) would be in my list.
IMDb, I think, suffers from over rating of flashy modern blockbusters (though none seem to have snuck in here) and positive feedback bias.
