Gonna try to phrase this an inflammatory way:
People who like bad movies have been conditioned by consumerism to not appreciate art. They believe spectacle, humour, and a tight plot are 'good enough', and they don't value thoughtfulness, novelty, beauty, or abrasiveness nearly enough. Film is more than a way to fill time and have fun. Film is more than an explosion, a laugh, and a happy ending.
On an unrelated note: Mad Max: Fury Road is one of my favourite movies.
Supposedly, a meltdown at sea is pretty low risk because you have the perfect heatsink literally everywhere around you, and its a molten salt design, which I think(?) (source: my ass) means that the fuel would at worst leak into the sea and immediately solidify back into some inert state.
