Return to the Blue Lagoon (1991)

The Blue Lagoon film from 1980 wasn’t received well by critics, but it did make a fuck-ton of cash (it was the ninth biggest film of the U.S. box office that year), so you can see how a dumbass film producer would look at that and think, “Fuck it, just make another one with practically the same story.”

Suffice to say, it didn’t go so well and failed to recoup its budget.
