3) Aliens(?)
Let’s be serious for a second: where on God’s green Earth did the idea of incorporating aliens into an Indiana Jones movie sound like a good idea? Indy discovers ancient relics that have at least some level of plausibility to them. And though I’m not one to say that aliens don’t exist, their presence in a movie turns it automatically into a sci-fi picture; and Indiana Jones is not sci-fi. Are we supposed to believe that the famed archeologist goes from obtaining the Holy Grail to picking up extraterrestrial crania?
The point to be made here is that previous writers have already dropped the ball while attempting to revive the Indy franchise. And if aliens were the best they could come up with, that is tremendously alarming. Fortunately, it’s already been announced that space-guru George Lucas will have no involvement whatsoever in Indiana Jones 5. It looks like we’ll have to wait and see what Disney has up their sleeve then; which leads to the next argument…
