Again, raiders did adventure right and nine failed the genre utterly.

The amulet is a great example.

It's a divine object based on divine mythology, which is all about specific moments and specific ordained destinies , so Indy receives the amulet from the other main character who is as much of a badass as he is and then discovering and entering the map room on the right day at the right time makes sense within the context of the movie.

It fits in with the theme of the movie and is very exciting, as an adventure movie should be.

Rey, having received the dagger from nobody important , standing on a random spot for no reason after nothing interesting has happened in the movie, notices the absurdly shaped dagger matches the island, but only from her perspective from exactly the spot she is randomly standing among the entire surface of the Moon.

Nothing exciting happens, nothing momentous, they all kind of shrug and say "oh that's it."

Raiders did it well, India frantic with excitement, and it makes sense within the context of the movie, nine failed utterly, made it boring and nobody cares even inside the movie.

As for your other questions

" Who maintains the traps?"

"'Why are the temples so convoluted?"

"Why design a building to collapse after the treasure is stolen?"

There is one answer to all three of those questions: to protect the sacred from the profane.

Whoever designed the temple was protecting a priceless artifact. The temples are convoluted to protect the priceless artifact. The traps were designed well to be maintenance free so that they would protect the artifact. The building is designed to collapse to protect the artifact from being stolen.

"You're thinking Raiders is fine (which it is) maybe because you didn't watch it looking for flaws"

The first thing I mentioned to you when you brought up raiders was that raiders does not make sense and has a bunch of plot holes, but is very exciting and works within its own story.

The problem with nine is that it is very boring and doesn't work within its own story.

It's enjoyable for you, enjoy it.

That does not make it a well-crafted or exciting adventure movie.

You keep saying that an audience member just has to ignore all of the elements in nine that are not good and then you'll enjoy the movie.

You don't need to ignore anything in raiders, it's a fun movie despite its flaws that it incorporates into its story seamlessly so that you barely noticed them.

Enjoy your movie, but so far you've made zero valid points trying to equivocate the success of raiders and the failure of nine.
