**SPOILER ALERT** I thought the scene in Indiana Jones and the Kingdom of the Crystal Skull where he escapes the nuclear blast was incredible. I mean, at that moment when I realized he was in a nuclear test site and there was no way out, I thought he was dead meat. And then he escaped in a fridge. I thought "wow." But it turns out that scene was so controversial that it coined a new term: “nuking the fridge, a scene in a movie so outrageous that it kills the rest of the movie or the rest of the film series. I didn’t think it was that bad, but thinking back…it was. I found myself asking, “Well, is it possible to survive a nuclear explosion in a fridge?" The answer is obviously no, but I thought this scientific explanation was good. Makes only slightly more sense than hiding under a school desk.
Oh, and in case you're wondering, you also can't use a snake as a rope to pull yourself out of a sand pit.
And speaking of George Lucas, here's more evidence that he is an idiot when it comes to good writing. It was his idea to put Indiana Jones up against aliens, which Spielberg and Harrison Ford correctly thought was ridiculous. I found the idea of aliens less believable than Indiana finding the Lost Ark of the Covenant.
