Raiders of the Lost Ark most overlooked flaw: Indiana Jones need not apply

The most overlooked flaw of Raiders of the Lost Ark is this:

Indiana Jones is superfluous to the story. Had he refused the mission and remained back at the college, the Nazis would’ve found the Ark on their own, brought it to the island, opened it and died the same horrible death.

Nothing changes with the introduction of Indiana Jones to the story.

The story’s protagonist is completely unnecessary.

Still, I love the movie.
