I didn't care for that, either. The movie tried to make Indy something of a kinder, gentler character when I liked him just fine as the tougher than nails adventurer he was in the first two who still had a heart as evidenced by him going out of his way to free the slave children in TOD.
Another thing I always disliked is the revelation he stole his fedora and jacket look from the guy at the beginning. To me that just cheapened him, to think his signature look wasn't even originally his own and he stole it from someone else. It made him feel inauthentic, for lack of a better term.
Agreed. Him acquiring every single signature aspect of his adult self in one 20 minute span of a single afternoon was just idiotic.
