Good one but I prefer Reservoir Dogs when it comes to Tarantino.
Shawshank and The Godfather are certainly amongst the best but then we can't forget Goodfellas, Taxi, Serpico, One Flew Over the Cuckoo's Nest, The Shinning, 2001 A Space Odyssey, Schindler's List, Raging Bull, Psycho, Vertigo, 12 Angry Men and so many more amazing movies.
