There’s an argument that George Lucas, Steven Spielberg, and co. should never have even bothered making Indiana Jones and The Kingdom of The Crystal Skull. The first three were fine as they were, so why not leave them well alone?
But that wasn’t to be, and they did produce an Indy 4. And it sucked.
This video shows how Indy 4 should have ended. Once Indy hides in a fridge to survive a nuclear bomb test, don’t have him brush himself off and then get on with things. Instead, call it a day and realize the game is up.
Then, start making apologies all round and move on. But not before you make sure Shia Labeouf gets mauled by monkeys in the forest. Because that is more believable than having them help him catch up with his father by teaching him to swing on vines like Tarzan.
