Seriously. Think about it.
All Indy had to do was let that Belloq dude take the medallion. He would have found the ark, opened it, and killed himself and all the Nazis.
Then the good guys swoop in with the greatest of ease and make off with the conveniently self-sealed ark and toss it in that warehouse.
Instead, we have to kill a bunch of Nepalese, burn down a bar, kill a whole lot of Egyptians, drag Indy under a car, annoy a bunch of African boat guys, etc. etc.
And then what? Bad guy opens ark and everyone who looks at it dies.
Waste. Of. Time.
Maybe the guys who do the "How it should have ended" videos can do that next.
