WaterWorld (1995) was Kevin Costner's obsession with creating an aquatic version of MadMax, with all the implications that entailed.
Despite the existence of computer-generated effects at the time of filming (Jurassic Park was released two years earlier), Costner steadfastly refused to use them.
The challenging conditions of filming at sea only compounded the difficulty of the shoot, resulting in a financial drain on Costner's resources.

Unfortunately, the film did not fare well at the box office, as audience expectations had shifted to a preference for computer-generated effects.
Rising reviews and negative accounts of Costner's passion project only added to his financial stress.
The plot of WaterWorld told the story of humans in a post-global warming world where the polar ice caps had melted, leaving no visible land, and Costner played a mutant hero with gills.
Initially met with scorn, the film eventually gained cult status.
Despite the criticism, I find it a guilty pleasure that I enjoy revisiting from time to time.
