Indiana Jones 5: 7 Kingdom Of The Crystal Skull Mistakes It Must Avoid
3. Jumping The Shark

Its not often that a scene from a film permeates pop-culture so much that it alters one of the most famous movie-centric sayings of all time. Fonzie in Happy Days may have brought us the infamous jumping the shark - a scene that signals a decline in quality, usually revolving around a ridiculous stunt or moment - but Indiana Jones 4 brought us the similarly poor nuking the fridge, and the film only got worse from there.
The preceding three instalments, for all their supernatural wizardry and gunfights, were firmly grounded in reality. Indy gets shot, held hostage, and generally, every threatening situation results in an appropriate injury for the characters involved.
But in the fourth movie, he could survive ants, car chases and explosions without breaking a sweat, and this removed a lot of tension. Like John McClane in the Die Hard series, Indy was turned into a superhero, when in reality, he's a normal guy in the wrong place at the wrong time.
Indiana Jones 5 should ditch some of these more extreme moments, and settle for some more grounded - but no less thrilling - peril for our characters to face.
