The whole theme was a really good idea, but i think the movie is poorly scripted. Events just seem to pile up in an unnorganized manner which make the plot a bit boring and confusing at the same time. Karen Allen's role seems more like a prop than a real character and Cate Blanchet's role is a bit too unidimensional (it would be funny if indy got to do her first before meeting marion again).

I would go into some more details, but yeah, its getting boring to write so much.
