Casablanca ★★★★★

Complex and simple at the same time.  Rewatched it with my daughter and it remains  truly magnificent with every revisit. 

Watching it this time I was aware of how long the setup was in the beginning, how much exposition there is. But it feels so lightweight because Curtiz uses the nifty trick of packing the movie to the gills with brilliantly watchable  minor characters.
