Count the cliff hangers and make the characters interesting. No wonder the story is meaningless dribble that goes nowhere and means nothing. The conception was never anything more than a series of empty thrills disconnected from deeper meaning. The ending was just a way of cementing that the story didn't actually amount to anything or make any real statement. Great that this entertains some people, but also notable that watching this film is one of the least rewarding experiences I have ever had.
I mean the story of Indiana Jones 1 is about the power of religious symbolism, nostalgia , history in general. It's not just about the actions of the plot but about how we see that era the film is set.
Nazis aim to use the Ark for power, Indy wants to put in a museum, ultimately it ends up hidden again in a warehouse. I mean seems pretty meaningful statement about how knowledge is used and controlled.
