I think Amelie is as good as it gets. This movie has it all beautiful cinematography, superb acting, good story. The other 3 are great in their own way. Blue Is the Warmest Color was amazing. An erotic heart-wrenching love story with excellent acting. Amores Perros was a powerful punch to the gut! I can't really say I understood Holy Motors, and I don't think I'm supposed to. It was such a wild ride and unlike anything I'd ever seen before. The movie is a sensory overload provoking many emotions.
