Harrison Ford playing Indiana Jones isn't a bad idea. There are five problems with Indiana Jones and it started with the Crystal Skulls.
Problem one, George Lucas. Way too much of this asshole involved. After the Star Wars incident this man cannot be trusted with beloved characters.
Problem two, Sheyaya LeBoufe. I think we agree and can move on.
Problem three, no Sean Connery. Stop being a baby, work for a few days of your retirement, get a ton of money, and join the cast. They need you.
Problem four, no John Rhys-Davies. Why are you not in this movie?
Problem five, Marion. Why is she frumpy and retarded?
Lets not blame The Berg or his Beard for The Crystal Skulls. The man makes awesome movies. If given total control while avoiding problems 1-5 The Berg would deliver on a new installment.
