Yeah. It just hit me. Indy loses- he basically gets thwarted every time, and in the end, he gives up.
And yet, when the movie ends, he's still the hero. Because he sure as hell tries.
The only thing Indy really accomplishes in the entire movie is to keep the Nazis from killing Marion in Nepal. Everything else, the total effect of all his effort is nothing.
Indy stays home, the Nazis kill Marion and take the headpiece to the staff.
Indy goes on the quest, he saves Marion and the Nazis get an incomplete copy.
Indy stays home, the Nazis dig in the right place and get the Ark.
Indy goes on the quest, the Nazis dig in the wrong place, and he digs in the right place, but Belloq and the Nazis get the drop on him and get the Ark anyway.
Indy stays home or goes on the quest, God kills the Nazis.
Indy doesn't
fail so much as he's really just the observer. The Nazis are defeated by their pride. In
Last Crusade, you can make a better argument that Indy fails, since without him the bad guys would never have found the Grail Cave. The catch again, though, is that even if they could have found the Grail without Indy's help, their own greed would have defeated them in the end anyway. Indy is able to figure out the correct Grail, but if he hadn't been there, he wouldn't have needed to.
In fact,
Temple of Doom is the only movie in which he finds a situation that wouldn't have resolved itself favorably without his help.
