Harrison Ford stars as Indiana Jones a grave robber, oh I mean Archeologist. He goes from quest to classroom fluidly, and then gets hired to find the "lost ark of the covenant". He finds that this quest tests his endurance.
Movies like this compel a person to root for the hero and boo the bad guy. You cheer at the end when the "bad guys" get melted by the spirits from inside the box.
I revisited this classic, since I have seen some bad movies lately. It is a good movie.
