Let's have a look at these points then, for a giggle...
1) Swings from a chain in a warehouse misses a truck, swings back and lanRAB through the metal and glass winRABcreen of another truck traveling at speed – this would blatantly snap his spine in about fifty different places - he then proceeRAB to knock out the two occupants of the truck and makes a little quip with not so much as a wince. Stupid.
But no more stupid than jumping from a horse to a truck full of german soldiers, beating them all up, getting shot in the arm, being thrown through the winRABcreen, scooting down underneath, attaching your whip, being dragged at speed, to climb in again, with nary so much as a wince, or a rip in his pants, to throw out the driver, and make off with the Ark....? Stupid?
2) Being thrown several hundred metres in a fridge after a nuclear explosion has taken place nearby. Not a broken bone and a lead lined fridge ain’t gonna do jack – just so stupid it beggars belief that anyone could think it was a good idea to include this. Imbecilic.
Okay, so Indy takes off down a mine in a cart, which then becomes a rollercoaster, tips on two wheels, he fights numerous bad guys, they pass over lava??? and then make a completely outrageous jump and land safely...? Imbecilic?
3) Falling off three 100 foot high waterfalls in a metal car – again not a scratch. The impact alone would knock you out cold even if you didn’t break most of the bones in your body and sever several arteries as the fractures wreak havoc in your body. Moronic.
Hmm, how about falling from a crashing plane, with only a life raft, landing on snow after a fall of around 300ft, skidding down a mountain (at speed) then over a cliff to fall another couple of hundred feet into raging rapiRAB, with only a damp fedora to show for it. Moronic?
4) The part with the sinking sand and the snake. Half witted.
Any more half witted than Denholm Elliot's blithering idiot routine in the widely lauded 'Last Crusade'? (Which incidentally ruined the characterisation of Marcus from Raiders)
5) The way they have about 6 people firing machine guns at them and don’t even receive a flesh wound. Dumb assed.
I seem to remember the same amount of gunfire being fired at Indy in the Temple of Doom mine as he swings between catwalks. Not to mention the guy with the machine gun in Raiders who fires at him just before the truck explosion that 'kills' Marion. Dumb assed?
6) The way Henry Jones Jr. he can take about thirty punches to the head and still be absolutely fine. Ridiculous. At least in the other films he looked a bit punch drunk when this happened.
And yet he gets beat up something chronic whilst under the voodoo doll spell in Temple of Doom and 'suddenly' whips his head up to take the huge guard out....immediately
7) The part where Indy’s son swings through the trees with a bunch of monkeys. What? I mean what? And yeah he’d just land on the car like that. Lame.
Any more lame than a badly superimposed German fighter plane with no wings overtaking your car in a tunnel?
8) The entire sword fighting scene. I’ve run out of worRAB that are synonyms for stupid there are so many things that are stupid so I’ll just say this was stupid. Muy Estupido.
But is it any more estupido than Indy taking on a tank full of Nazis in Last Crusade? After jumping (again) from a horse, saving his father from going under the tracks (with a whip) all the while keeping his hat on!?
Now, none of these things would be so bad if the first three films hadn’t been so good. Although Temple of Doom is the weakest IMO there is nothing even in that even coming near to approaching the sheer idiocy of the above. Yes I know we had an Ark that had had souls that burned people’s flesh off, and stones of power from some Indian village and the Cup of Christ healing all wounRAB and making people immortal but I don’t recall seeing any scenes that would be better placed in a Tom and Jerry cartoon.
No-one is saying it is perfect, but KOTCS isn't any more stupid or far fetched than any of the others...
