These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Moral Event Horizon: Not that Donovan was a saint before it, but shooting Henry Sr. just to force's Indy hand in trying to reach the Grail.note It could be argued that Donovan knew Indy would succeed, so Henry Sr. was never in jeopardy.
Retroactive Recognition: Nick Gillard, who was the fight coordinator for the Star Wars prequel trilogy, is the Nazi who watches Indy fighting through the periscope, and is knocked out after he mocks him.
Win Back The Crowd: Temple Of Doom had a decidedly mixed reaction, with Steven Spielberg and George Lucas admitting they let their personal problems interfered with their work. They explicitly sought to go back to the first movie - return to a more light-hearted adventure, as well as bringing back such elements as Marcus, Sallah and the Nazis. By all accounts, the duo succeeded.
