So i take it you don't like Kasden's serious take on the story crafted from old hollywood films like Casablanca?

Indiana Jones is not the place for trying to keep to seriousness. Pointless exercise in futility. Nor am I interested in a story ripping off Casablanca. Or the old serials Lucas is so fond of. Any more than I want Star Wars to be some corny old serial from way back. If Lucas sees them as his inspiration that's his problem, but the franchises are much better evolving beyond that stuff. And I'm sure some people will be horrified, but I've never been terribly impressed by Casablanca.

They made Marcus into a retard in last crusade

Marcus as a comical character is more fun than Marcus as a vague background character.

Plus there are cringeworthy moments like indy putting a rock into one of the side cannons on the tank and it blows up in the gunners face like this was like Looney tunes and not supposed to be in real life though actually fiction.

I don't see the problem with that. If I wanted realism I wouldn't be watching Indiana Jones.

Then you have both shortround and willy in temple of doom almost a equally annoying as jar jar binks.

Short Round was a good character. Willie was a bit annoying but not half so annoying as as one would think she would be, because she was acted with life and enthusiasm.

If not for the mine car chase that was in the original raiders script and the shanghai scene at the beginning the film is worthless.

The Shanghai scene was good, better than most of Raiders.

Then you have the raft falling out of the plane as their parachute.

Not a problem. If I wanted realism I wouldn't watch a film trying to pass off that Jones guy as an archaeologist.

Then in Indy and the crystal numbskull you have him riding through the air for three miles in a lead lined fridge. And somehow the russians also magically outrun the blast.

I agree that was going too far. Just because it doesn't need to be strictly realistic doesn't mean it's ok to go wildly in the opposite direction.
