I say a 'simple' story because I am writing this piece after almost 77 years of the film's release, but in 1942, this story would have been quite original and new. The film naturally and flawlessly integrates a moving love story with the War backdrop. Bogart and Bergman make you feel the love through their expressions and emotions. Top-notch acting by the entire cast makes Casablanca one of the masterpieces of the 20th century. The film is crisp and fast and manages to keep you hooked throughout with its thriller element. With so many stories going on, you will be hooked to the screen.
