BTW, I think KOTCS is 90% great movie, 10% WTF. One more script draft, a little simplification and set of fresh storyboards would have made it second only to ROTLA.
Fridge survival - OK
Flying fridge - Over the top
My suggestion - Fridge collaspes into underground mine shaft that subsequently closes in after blast which shields away the majority of the radiation fallout.
Crystal Skull Aliens - OK
Temple that turns into transdimensional UFO - Over the top
My suggestion - Aliens do not come to life but in the spirit of the 50's B-movie aspect they were going for the 13th skull is a key to the trans-dimensional portal that causes the temple to collapse. Classic temple escape - minus Alien mind-zapping Spalko and giant flying UFO.
Swinging from vines - OK
Swinging from vines with an instantly befriended pack of wild monkeys - Over the top
My suggestion - Rabid monkeys actually attempt to attack Mutt, Mutt gets away when Russian soldiers become victim of monkey attack. Mutt is reunited later with a grieving Marion who thinks she lost her son.
My suggestions keep these story elements, but give them a simplified explanation.
Nice, theropod! I agree, just a few simple changes would have made the situations feel more plausible and would have greatly benefited the movie. That's the major thing I feel Raiders did right compared to the other three: it managed to feel more plausible and grounded, despite some (arguably) outrageous scenarios.
