ROTLA owed a lot in genre to the early Connery Bond movies. Think Dr. No, From Russia With Love and Goldfinger. Then along came Thunderball / Temple of Doom.
By the time we get KOTCS the analogy would be the later and campier of the Roger Moore Bond offerings.
Just as Bond had to throttle back (the Daniel Craig era), I hope it's time that Indy can also throttle back a bit.
The question, then, is: would Dr. No set the world on fire if released today?
It's hard to go back over broken ground, and as I wrote above, it would be a brave move.
Now I liked the scene for its absurdity. Yet, film can't show a character's feelings without words or the visual frame of the character's face. The scene conveys much more in text, in flight and post-landing. As it stands we have to amuse ourselves with the sight of a flying fridge. If Indy had done this at the end of ROTLA in order to escape the power of the Ark it would have been way out of place. Yet, TOD and TLC prepare us for the event. It's a logical step for a character who over the years increasingly defies logic.
Same goes for the waterfalls, the monkeys, the snake in the sandpit etc etc. Maybe just one of those scenes, but all of them add up to so much more than their total. For me the fridge is still a keeper. A few less other wild rides could have made room for more suspense, more exploration, more mystery, all accompanied by witty character-creating dialogue. That would have made me love the movie, rather than relegating to the merely "likeable" stack.
