A better Indiana Jones sequel would have been set in the 1990s as two trepid investigators find the CIA documents about the Ark Of The Covenant and everything else in that warehouse and go on merry adventures.
I've always liked the notion that the Ark is some mad radioactive rock that has to be kept in lead until the (suicide) pall bearers drop the lid and the skin starts to melt......hours later going by that Chernobyl series.
