Senior Jones not remembering the 3 traps...
... was something that I didn't very believable. I enjoyed the movie very much but that part kinda took me out of it. I mean an ordinary person most likely will not be able to remember a map, but Indie Sr. not being able to remember the three (rather simple) traps and their (even simpler) solutions seems a bit odd.
And this is a guy who spent most of his life researching the grail. That was the only thing he ever thought about for years. People like that usually know everything about their obsession by heart.
It seemed like a b it of lazy writing to get the duo back to Germany. Maybe the writers should have come up with another reason for that. But these are just my opinions. What do you think?
