Saw this last night and I thought it as terrible. It was two thing an Indiana Jones film should never be, dull and depressing. Helena was one of the worst characters I've ever seen. And the very ending was atrocious.
Spoiler:
Indy should have chosen to return not been knocked out and brought back back. It removes all agency from the character and leave his arc incomplete.
I'm a bit surprised by the online reception overall. Give it 6 months and I expect this will be considered worse than KotCS.
