And the film is not bad. There are thousands worse with similar ratings.

Okay, my take: this is not a must, and yet some nice scenes, some gorgeous acting on the side of the heroine. Maybe what many Hollywood -trained spectators miss is the clear-cut good and bad?
But that'd be typical for Buñuel: his world isn't split into good and bad, and he doesn't do happy ends. This definitively shows: you can have your sympathies and your antagonisms with however you like, he or she will disappoint you. This film isn't much different: whatever good happens, it will always fall back to the bad guys, who will use it for their own purposes.
And in here we see a man driven by the sense of justice, and he'll succeed. Not. Any step taken, or at any achievement someone will pop up and steal the victory from him. He becomes a national hero, only to find himself in another conspiracy against the leadership. And in the end, his one and only true love leaves him. She has gone all the ups and downs with him, but can't follow his never-ending moral vocation; as much as it is warranted.
Any moral from the movie for me? In the end, when we have gone our path, we will be alone.
